The future of social web apps

I came across this article published on thinkvitamin.com. I found there many ideas which are similar to mine:

Like you, I’ve got a million things to do and I’m constantly battling to keep on top of my inbox and RSS reader. The last thing I want to do is add another thing to that already-way-too-long list.

I like web services such Flickr, del.icio.us, Gmail, Bloglines but I don’t use their social part too much. Maybe I’m not so social person or maybe I don’t have enough time.
Anyway, the article is useful to understand a conception of social (and not social) web apps in the future. Moreover, there are a few new services which can be interesting for you. For myself I discovered Netvibes – amazing place which may agregate a lot of others web services, LinkedIn – resource for linking with business partners and Basecamp – service, developed by 37signals and offered TODO list, file sharing and more. But last one has too expensive price for me.
