For those, such as myself, that enjoy FREE online music, visit grooveshark.com. My colleague, Jacob recently told me about it, and I have been enjoying it immensely. It is different from pandora.com because it lets you be your own deejay, and you can listen to entire albums from your favorite recording artists. Enjoy!
On that top 100 list I had probably seen almost half of those sites, so I decided to try something completely different from anything I might be interested in...Stardoll. It's actually kinda fun!! I made my own paperdoll to resemble (barely) me and now I can dress "me" up in whatever I want to! I can even choose from celebs and dress them up. I might be wasting a lot of time learning a lot from here today! I'll check out other sites after I'm done dressing myself up...
One thing that I've been hearing about, but that isn't live yet is Google Wave. It's being mentioned in most of the blogs as the "next big thing" so keep your eyes and ears open :)
It does sound interesting, although one of my colleagues made the comment that Lars sounds a bit too proud of himself. I liked the commarady between the different teammates, though.
