There's publishing, and then there's publishing. A general-purpose CMS often needs tweaking to meet the demands of a professional publication — such as a magazine or news organization.

Proprietary social networking platforms have a few distinct issues for free software users, but one of the biggest is that it is often hard — if not impossible — to extract your information from them.
