Is there software that can keep track and notify me of new posts across messageboards and sites like StackExchange (across multiple different usernames)?
I would like it to have the following features,
- RSS Support
Well, if there is an RSS feed for your profile, that you can use an application like feedreader.com to track it,
Otherwise, what I do is I use a Firefox Add-on called Distill. It basically takes snapshots of a webpage an alerts you if it has changed. You can choose to ignore and/or only look at certain elements on the page (For example, your Stack Exchange inbox). Distill is also available on Chrome, Apple, Andriod, and as a web service.
Distill is a web monitoring tool. It can monitor RSS feeds, a webpage or a part of webpage. Alerts in the form of pop-up, audio or emails can be received.
In addition to basic page monitoring & alert, there are advanced options to give more control. The monitoring interval can be set from arange of values. Various conditions can be set for the alert action to occur.
