Alternatives to using email (in particular, Outlook) as a knowledge store? [closed]

I use Google Mail for this. The global search combined with the ability to tag things is very powerful for things you know you read but cannot remember where.

"As someone who has been using email since the 1970s, I've tried just about all the usual routes. However, I've settled quasi-permanently into this scenario:

I use mail filters to scan all my old mail files and pull out mails of
interest into basic categories - as COPIES, not moves!
I save raw in-box postings as-was, but move them, with the date they end
as a part of their file name, into a subdirectory specifically for these
inboxes.
I use grep to find what I want - from the file system. It gives enough
granularity through file system mechanisms.
I then step back to a mail reader to read the items found via grep.

Note that grep can give you a window before and after matching lines. A little clever scripting gives you a pretty robust search capacity and you can manage it all on your own disk space...

Finally, no way in the world I would use Outlook - it's just troublesome malware if you ask me. I want access to my raw data, thank you!

"You can try using Xobni as an Outlook extender. It has better search, and better organization capabilites as well.

What I used to do is to host a Wordpress installation in my localhost and just post snippets of information here. :P"

If you have less than 1GB, I would recommend the perhaps off-beat use of Posterous. just forward all the emails you want to save to post@posterous.com and you'll be greeted with an editable, searchable blog. Woot! you can of course make it private.
