Someone at my work found out about this blog and, being a twit*, comments on it constantly.
Some of the joy of blogging is just getting the post out there; and having someone looking over your shoulder so to speak can be disconcerting to say the least.
I've found Marc Andreessen's blog now, from a link at lifehack.org, and a great post on productivity -- I love the bit on the inbox, as well as the "don't keep a schedule" idea. The best tip for me was the lead to stuff on using procrastination as a tool. Since I'm a world-class procrastinator I'll have to give it a go.
* yeah yeah, you're not a twit.... much :D
