Yes I use them for my Site
http://markitzero.site90.com/ and a few others I like them because they are the only decent Free Webhoster that I have found So Far.
I will tell you if your site gets less then 10 visits a month they will start to do a Auto Subdomain cancellation thing and they will send you a Email when it gets to that stage and you can go into the your account and save it from cancelling so they are very good. You can purge a Subdomain or even add more like I have. I will tell you that there MySQL server can be flaky something because they are shared be they come back up shortly after, I rarely have the SQL Server going down.
