Once again - given recent revelations of extensive, indiscriminate and intrusive cyberespionage over all digital communications using software and hardware crack-ins - there is no "recipe"to give any user any degree of "anonymity" until the 4th amendment is respected and enforced by governmental institutions and a reasonable degree of privacy online is feasible. A complete inspection of hardware, software, encryption protocols, etc is in order before and decent implementation of privacy measures can be considered. Perhaps we would need to throw away all the internet enabled devices we have purchased over the last 20 years as well as all the windows, apple and android machines and start over with an open source, clean operating system. Hardware companies would need to follow some sort of ethics code and keep their devices clean as well, not selling consumers hardware that has been tampered with to allow for cyberespionage and other unethical activities by third parties.
If you're looking for anonymity in terms of social networking, then you should check out Ravetree. Unlike facebook and google+, on Ravetree I'm allowed to make anonymous posts, comments, and even write anonymous reviews. I've already started to get some of my friends using that site. It's actually better than facebook overall (at least that's my opinion).
