One problem I've encountered when I've sought to check out other blog sites is that you have to join first. With Blogster, for instance, I couldn't tell until after I created a blog that I didn't care for the site because it apparently failed to call other bloggers' attention to new postings as mybloggers does. Consequently, I felt as if I was talking into the unresponsive blogosphere.
I only just heard about tumblr.com. Does anyone have any knowledge about this blog site? I went there and before one can get in to see it, one has to join. I'm uncomfortable with that.
