Yes, it takes some effort to get your blog read here, as new material is posted by the minute and there is much to compete with. If you are just going to post something and then sit on your hiney waiting to be deluged with visitors, this ain't the site for you. However, if you are willing to visit and comment on other blogs, you'll have your hands full soon enough.
The site is free to use and UNMODERATED. That means you'll need a thick skin, because over the years the site has attracted a larger number of trolls than comparable sites, and while you can block them from commenting on your own posts, there is no 'ignore' feature that would prevent you from seeing their provocations on the posts of others.
Even when a troll discovers they are blocked from a majority of the active blogs there, they do not go away, they merely create a new account and carry on. This has led to a degree of paranoia among the more established bloggers there, and "new" people are often looked up with a degree of suspicion, making it not-exactly-friendly to genuine new users.
That being said, if you survive the gauntlet you will find decent and down to earth people to interact with, and despite the sites lack of moderation, they do have a couple of hardworking volunteers that keep it mostly spam-free and will report glitches to a techie for you.
