Hi Tim
I wasn't actually expecting a personalised response from the AnyAsq creator.
It was more a general comment, and the question still stands I think - read my DM's?, no frickin' way!! - that's a serious invasion of privacy ...
I understand that you have to do what you can to spread your product, but there's a trade-off between being able to tweet, and asking someone to basically give up their twitter accounts to you ... you're going to lose more potential customers than gain with this method IMHO ...
How about: asking someone to sign in twitter, and asking their permission to just tweet their questions? - could you limit it to that ?
