So I bit the bullet and moved my personal site to Squarespace. I love the look and feel of the templates, the easy, intuitive content management system. I like how clean and smooth everything feels. It also gave me a nice excuse to clean house, so to speak - so I have not moved over everything from the old site - blogs that I never updated, for instance. If there is something in particular you remember liking from the old site, feel free to shoot me an email and I'll see about getting it to you.
There are a few things about Squarespace I'm not totally thrilled about, so it did take a lot of weighing and agonized decision making - there's no general FTP access (there might be with a Developer Account - I haven't taken a look into it), so Flash games that dynamically load in xml files and such are going to be a challenge to post. Also, there are no subdomains, so if I want to create a separate site for one of my musicals it will probably have to be hosted elsewhere. There might be ways around these restrictions - and if I find anything I'll be sure to let you know!
