What Web apps increase your productivity?
embeddedradical: webnotes.net (found out about it here, been using it since), google reader, vitalist, a personal IT wiki (using screwturn wiki), and the gtdish setup i got going on on my usb drive (truecrypted w/ backup script that creates a backup whenever im plugged in at home, maintains last 7 backups [each unique day, in case i backed up again on same day for whatever reason]), oh ...and jquery.  i know, not all webapps, but those are the things that help me out the most.
