basic categories are:
1. Messaging - Scraps, Private messages and now a days something like status :)
2. Network/Friends - people already you know or second level (most probably you can cover the entire world at level 6).
3. Classifieds - Post ads purchase/sell.
4. Jobs - This is the only feature i think any networking can extent to second level, still from past a decad it is in its standard shape
5. Blogs - very common
6. PROFILES - theirs nothing effective - I like to show my profile to impress people - technicaly grow my network :P ........... same old profile - my pic, my place, contact ............ Can't theri be a thing Which is my own and I like to ....... :(
people have to think beyond this, now a days every week or so you get a mail "Join my network on ...." what to do? All look the same
