Finally, something for us [few] PC users [left] out there to get excited about! The Beta version of Google Chrome has launched today, and it's only available for those of us fortunate enough to be running Vista. My initial test run of it here is looking pretty good so far - I'm loving the visual representation of your most visited websites as the default homepage. Check it out here!

I'll just come out and say it. I love Tumblr. The whole concept behind "Tumble-logging" (or quickly blogging and posting links and media as you're surfing) takes away the tediousness of having to sit down and put a lot of thought into a full entry. Of course, this is both good and bad, but for the purposes of sharing cool stuff you come across, the simplicity can't be beat.

I was a bit nervous today, however, when I saw that Tumblr is testing its new beta site. I was so concerned that the simplicity and straightforwardness of the interface would be sacrificed for "new" stuff. But I was pleasantly surprised - those Tumblr guys know what it is that makes their product great. Check it out here!

A friend just turned me on to this delightfully simple work log, ididwork.com. The name pretty much says it all; log the work that you did, tag it if you like, and ididwork.com will create charts mapping your work, email your logs to your manager (if desired), and schedule work reviews. This is a handy little tool for jobs where you have to log hours on certain projects, or you may be working on site and have to report in your work to your manager. Just a great example on how simplicity wins over and a site without too many bells and whistles can be most useful.
