My three pick for the day are:

Very cute UI, super simple, online editor, though the restriction to avoid abuse stopped me form uploading my website which contained sccs files, once deleted, the upload worked with a single drag&drop. After the free tier, there is only one tier at $5 a month, which gives you CNAME (custom domains), generic SSL and remove the restrictions, definitely chromebook friendly - would recommend for 1st time users and kids. But the lack of versioning or automation (beside the webdav mount on the payment tier) is a no-go for developers. - https://www.dropbox.com/
There is a lot of documentation on how to host a website as a shared dropbox folder, but no matter how hard I tried, that feature doesn't seem to be available through the free account setup.
