I have lists of ideas. Despite their dubious quality, I would like to be able to present them to the public in an filterable, searchable and readable manner.
An idea is essentially a super-simple blog post with only simple formatted text  and image content. I would like to be able to tag them and provide an interface for sorting them, so others can easily browse them.
The requirements would be:
- Creation of simple posts with formatting
- Allow creating of post templates with pre-defined fields
- Post browsing view allow for sorting by tags, which can both be numerical (range from 1 to 5) or categorical.
- Post reading view separate from post browsing view
- Ability to link to individual posts
I currently use Google Docs (example) and GitHub issues (example) for this purpose. However, GitHub issues does not allow for numerical tags nor sorting of numerical tags. It's also a bit confusing to link someone to.
Google Fusion Tables was really close to this. However, it's viewing mode and the ease of editing text inside that interface (it requires raw HTML to be input) is less than ideal. Additionally, it is not possible to link people to individual entries. Regardless, Google Fusion Tables has been discontinued.
Airtable is also really close, but doesn't have anything close to a mark-down formatted cell.
Wikity is an admirable effort at taking this idea to it's logical extreme and building a rational, investigative social network around it. However, the project is dead and the interface is so messy I don't know how to navigate it.
 By "simple", I mean what the StackExchange markdown editor for this site already supported by this website.
