A comment for those seeking to use this site for personal gain: Given the increase in requests, let me be clear. I write on this blog because I want to. It’s my hobby, my playground.

And if you think something would be of interest, differentiate yourself from the spammers by referring to a posting — in an intelligent way. (I get enough auto-generated mails to identify them immediately.)
