I'm trying out Square Space in hopes of moving my blog/website hosting to their service. There are likely to be a lot of weirdnesses as I play around with posting, appearance, functionality tools, etc.
So far, I like it! It is true WYSIWYG, plug and play interfacing at its best. Very nice for someone like me who just wants to type up posts and hit "Publish" without messing about with scripts and styles and codes and whatnot.
