Shameless plug, I use www.thebuckyball.com to handle all email contacts and social friends, but that's because I wrote the backend, (in erlang) for those interested.
I have just stared learning Erlang after more or less leaving Java, and the heavy weight world of J2EE. I was surprised how easy I have found learning Erlang maybe it just seemed to make sense, or it feels like the right way of doing things. I would be really interested in the book.
Also "Apophis, a 25 million ton celestial body will narrowly miss our planet three times in succession.
The first near-miss is expected on the superstitious date of Friday 13th 2029" That's not the best day for it to happen is it.
