Dreamhost offering free web hostingDreamhostapps.com seems like a decent, free way of setting up managed, security-maintained sites using popular free web software (with noticeable limitations on themes and plugins).

Dreamhost is currently my preferred provider of tinkering friendly shared hosting. I subscribe to their main product, a hosting plan ridden of unnecessary restrictions, which also includes nice stuff like a reliable, sanity and time-saving WordPress one-click upgrader and a feature-complete control panel. Their service is reliable enough for non-business stuff.
