Hi, For the algorithms our inspirational reading was "Programming Collective Intelligence" http://oreilly.com/catalog/9780596529321

As all the recommendation algorithms the basis is the text, and dictionaries with technologies, and of course a long time blacklisting words by hand.

We didn't think about ssl but, could be a nice feature. Is already wrote down in our roadmap. I like it.

About http://www.foaf-project.org/ give me some days and I'll put it. I can tell you when this is done through GitHub's message system.

We are really appreciating and considering every ideas all of you are giving here. Thanks a lot.
