I use FB to keep up with friend I have spread out over the globe )ie a Japanese friend just had a kid). Half the time I can't read what they post and Bing translator sucks liquified monkey ass but I get the gist of what is going on in their lives. The other part of the time I'm asking work related questions, again to a group of people who do similar work. The work questions confuses all the non-science friends I have.
