simplelist: the 10 common ingredients of a social media website

The guys at Nettus have written about what goes inside any good social media website. However, they forget to write about the code snippets for each feature but I think you can search for the codes on Google with little fuss.

Here's the list:

1. Activity Stream e.g. Facebook
2. User Authentication and Profiles + access levels
3. Invite a friend an "invite your friend" script that furrows into your user's email address book and does at least one of two things:
4. Recommendation Engine - Many of these content recommendation engines are built on the Slope One Algorithm http://en.wikipedia.org/wiki/Slope_One
5. Private Messaging
6. Status Updates (Like Twitter - get Laconica and build your own Twitter http://laconi.ca/trac/ )
7. Multiple Ways of Viewing the Data
8. An API http://3scale.net/
9. Voting
10. Widgets http://www.widgetbox.com/
