WordPress.com is open! After working with invites so far, it’s now finally open to signups. So, if you’re looking to setup a WordPress blog without any hassle (not that it’s much of a problem to install WordPress, especially due to the fact that most hosters offer one-click installs these days) and can deal with some restrictions (as far as I can tell you can’t point a domain to your blog, but you will have to stick with the username.wordpress.com domain, as I don’t want to signup just for testing around I can’t say much more about it, but I guess that some other restrictions most certainly apply (plugins, etc)?!), WordPress.com is for you - especially because it’s free (at least for now!)
