The best tools to save me time… GTD

I was at a leading law firm this morning talking about Gist and other tools we are using to make use more efficient at gathering and/or processing information. I started this list;

All the time;
www.gist.com – gives me all the email messages, tweets, news, blogs… about the people and companies I care about (automatically)
www.tweetdeck.com – my twitter reader
www.activewords.com – to save time doing repeat tasks, especially responding to email
reader.google.com – my RSS reader
tamccann.blogspot.com (blogspot) – my personal blog
blog.gist.com (wordpress) – corporate blog
www.getanagram.com – quickly grab signature files and create Outlook contacts

Sometimes or passively;
www.disqus.com – tracks my blog comments across multiple sites and blogs
www.gravatar.com – allows me to manage my profile photo in many places
www.evri.com (new entrant, I also worked on this worked on this at Vulcan) – I have created “collections” for key topics and competitors
www.clearcontext.com – outlook add-in that organizes email into projects
www.friendfeed.com – tracks posts and stuff from my friends across lots of different sites and services
www.tripit.com – makes my travel more efficient and somewhat social (I can see when my friends are in town or I am near them)

I am sure there are lots of other tools listed on sites like www.lifehacker.com, but what tools are you using that you really like. Leave me a good comment and I can hook you up with a www.gist.com beta account.
