They offer a set of comprehensive shared hosting plans. The feature set provided is fairly complete and useful for shared hosting of web applications. However the usage limits are fairly tight. They do explain that "most of you don't need 400gb of disk space" which may be true but at the same time their largest hosting plan only offers 5gb of disk space and 10 gb of bandwidth. That isn't much especially in todays era of large multimedia files. A podcast for example could easily outstrip those limits, and this is their largest plan?
They claim to be "green" and this claim is backed up by purchasing renewable energy credits.
