I've decided to revive my Gather site which never really got off the ground. There are so many awesome new sites out there that I feel like are more modern in their look and feel than Livejournal, like Gather and Multiply. I like the concept of writing articles. I think it would be good writing practice, and a good incentive to develop new theories and interests.
I haven't found any writers or categories I really want to follow yet, unfortunately. They have so much great technology and means of communicating articles of interest to you, unlike Livejournal. I have been feeling lately the need for new inspiration and new mediums, and this is a great new thing to play with, at least.
