One stop shop...

Hey, don't normally visit or post in this part of Captaincynic, so my apologies if this had been brought up before...
I like the features of Gmail, with Googledocs...
I like the features of Facebook with all its networking tools...
I like search engines, and the idea they could catalogue previous searches, and update search results, based on new postings...
I like personal websites (free ones particularly)...

What I'd like to see would be one application that encompasses all these factors. It could be based on a browser, perhaps with password access. It should be free... I think having all these features together could save time.

Please respond if you've heard of anything along these lines, or if you'd like to see something added to the list, and if you've any relevant comments.
