Personal Information Management

So, these are problem statements ...

1. I know a lot of things and want to know lot more.
   
2. I read tons of material and my to-read list is growing exponentially everyday.
3. I come in contact with a lot of wonderful people. And I need to stay connected with them.
4. And finally I want to be able to manage my todo list on a daily basis.

And with busier and mobile life, its imperative that something about managing information is done. And fast.

I have decided I would use online tools for these tasks. Simply because Internet is now as ubiquitous as it could be and online tools are almost as good as offline ones. Also I want to use simple tools. Life is too complex anyways, why use complex tools?

So, here is a list.

1. A pen drive for files that are too large to be shared on the Internet. And carry along data that is very critical that if Internet goes for a toss.
   
2. del.icio.us - bookmark links, webpages and other things that I want to keep track of.
   
3. pbwiki - take notes and invite comments
4. Google Docs, Calendar - for creating lists and schedules
5. Google Reader - to keep track on my reading list
   
6. SaurabhGarg.com and septemberthe22nd.blogspot.com
7. Slideshare and Scribd - for managing files, documents and presentations
   

And then I will continue to use these online tools/services

1. Twitter
2. Dopplr
3. Facebook
4. Flickr
5. LinkedIn

What else should I use? Is there a good contact management software? Where I can keep a list of my contacts, where I know them from, what do they get to the table and all that?
