I think Buffer would best solve your purpose.
Buffer is an auto-posting service that’s widely used to schedule posts to Twitter, Facebook, LinkedIn, and even App.net. In addition to these services, Buffer has recently added support for Google+ Pages. This support uses Google’s official API, so Buffer should work very well for people who need to schedule ...
My recommendation would be Hootsuite. Hootsuite is social media management dashboard where you can manage multiple social networks directly from Hootsuite (Facebook, Twitter, LinkedIn, Wordpress, Google+, Foursqare) or by adding available apps (Flickr, Youtebe, Gmail, Instagram, Reddit, Pinterest and others). Hootsuite permits scheduling tweets and messages,...
I understand your question because I've been wanting to create a company / app solely to address this gap. There is nothing in existence currently that will directly fill your need with excellence I must say, although I'm sure eventually it will come. In the meantime, people are using the following primarily:
You might want to use OpenID.
At the server side, you can use one of these libraries: http://openid.net/developers/libraries/
At the client side, you can use OpenID selector: demo
If you want a custom solution, you might need to develop it by your own. The documentation for authentification methods of the big providers is pretty good:
Unfortunately, I didn't find a standalone application that you can schedule the post on multiple social media accounts. If someone already found it, I hope it will post the application soon here.
I recommend the web application which opposes the question above. You can use Buffer application, they offer you start for free. You can schedule the post as much ...
Seeing general recommendations would be great, but it's worth pointing to two related websites that enable something like this in the effective altruist movement:
http://skillshare.im/ - lets EAs offer and request goods and services from one another, to help each other out
http://eaprofiles.com/ - EA Profiles, which let people share their interests, skills,...
This sounds like the sort of thing that a closed community on Google+ would be ideal for, if you set up a closed community only those accepted into the circle would see the content:
Each member has their own login/password Their G+ Identity
No "friending" necessary, all members see the same thing Yes
First thing seen after login is the message board ("wall"?...
You could use If-This-Then-That, otherwise known as IFTTT
This is a web service. Many social media sites are covered by its range. You can create recipes such as:
If I post on Facebook
Then Copy the post to Twitter
Create a number of such recipes to copy onto the sites that you want.
They can be adjusted to copy just text or pictures if you wish.
You could use the "Network Import Example" Model from Netlogo and customize it with code from the "Network Example" (which shows an animated graph with links flipping around). Both Models are present in the Models Library (= preinstalled).
Maybe its not your use-case and maybe it's too much effort to learn the new programming language. Maybe you need to ...
You could consider google's reverse image search. I know in Chrome it's available in the right click context menu, however it is accessable via URL. Your avatar for instance, returns a result like this. I'd be curious to know if the url arguement is just an encoded version of the image file.
You could do this in R:
# some newer libraries for dealing with networks
#read in data
txt <- read.table(text = "
Partner_ID Child_ID Relationship_Name
A A1 Normal
B B1 Custom
B B2 Custom
A1 AAA Custom
B1 B1.1 Normal
B2 BBB Normal",
header=TRUE, sep=" ", stringsAsFactors = FALSE)
# table (data ...
There are multiple open source tools that can manage social media accounts for you. Here are two:
Socioboard offers an open source version and a commercial version. It supports Facebook, Twitter, LinkedIn and Instagram (but not Google Plus). From the website:
Socioboard Core is an open source social media management, analytics and reporting ...
There is no emulator of snapchat itself (that I am aware of). However there are plenty of android emulators available for PC with support for the google play store, meaning you can install snapchat onto the emulated android OS the same way you would install on a phone or tablet.
Android emulators like Andyroid or BlueStacks will do what you need (both have ...
You could try out "kintone".
It has features to create multiple databases (which they call "Apps") via GUI, and you don't have to be an IT expert to create/edit these.
It also has a feature called "Spaces", which is like a forum for teams to share information. You can have club A creating and using their own "Space", and club B creating and using their ...
You might find Tiki interesting. It's a self hosted groupware platform and wiki that supports all of your listed features either built in or via plugins. It's actively maintained and as a very large community.
I also tried it for a project but it was just too powerful but maybe it's exactly what you need.
Lost Circles (link to their website) is an extension for Google Chrome that maps your Facebook friends in a network.
Link to the Google Chrome store
My sales pitch
The software is specifically aimed at Facebook. It's not as extensive as you describe, in fact it only looks at your Facebook friends and looks which of those people are also friends with each ...
Currently the best option I found is sharrre.com.
It supports sharing on:
Here is HTML to create a Tweet button:
You can pass data attributes and script will pick them up for you:

I think bufferapp.com does what you want. I'm unsure about facebook promotions as that's not something I've used. It has the other features you've listed.
They have a free version, premium versions start at $50/month.
Going along the idea of Steve's G+ answer. What about Facebook?
I know it's generally considered more of a public thing but you can set up private and secret groups that allow you to interact in all the ways you mentioned.
It is widespread, works on every almost every platform going and most people will have an account anyway.
I haven't used it for almost a year, so I'm not sure how much, if at all, it has changed. However, when I used it, Buffer was a great service. They do have a free plan, which, unless you're running an organisation or business of some sort, should probably be enough. And if you really need to have some major s**t going down, then see here.
