@tcql Yeah, I was wondering less about blocking and more about how people would feel about it. Elsewhere I value keeping up with what people working on behalf of issues that are important to me have to say. I use twitter to read much more than to write and follow ten times as many ppl as follow me. I don't get that as much here (yet).
Regarding tagging you in, I've just noticed that you have helpful input when I see you come across the timeline :-)
