Main point: Tim lays on a really good range of interesting rides and breaks new ground. These are an example and seem ambitious and probably audacious. Please do more.
Drivel: There seems to be some ?illusion? that emails can somehow be kept 'secret'. I am not sure this is the case I am not expert at all. However because of this thread a I poked around and used an app that makes a pretty good job of identifying an email address from say an entry in Linkedin. I think it generates likely emails and then pings until it gets a hit. Hits come back at three levels of certainty.
I work on the assumption that if I participate in Social Media and use a Mobile Phone that all is essentially public. So I have a choice participate but understand this is a public act or not participate. If an org. contacts me I would assume they had my email either through emails from me or through emails from others that had my email in cc rather than bcc. But they might have picked it up from my workplace or places like this. I do get junk emails (about 16 so far today. They go straight to their own folder which then gets wiped. The web is very much a two-edged sword and trying to make it work the way you want not at all easy.
Cnut (a much-improved spelling of Canute) showed us the problem.
