I'm pretty sure there are no questions that embarrass me: i embarrass me, but questions don't. And i will do my utmost to not embarrass you in my answer.
One thing that really embarrasses me is my continued lack-of-follow-through on the too many things that i want to follow through. I usually eschew such invitations because i feel i am asking for failure, but .. try, try again.
Also, with friending memes and tumblr refugees, i welcome introductions to folks whose company you think i would enjoy.
