Just saw your link to the "smart way to get my attention" article, bit.ly/nSUJbH. You might want to try Shortmail as a way for people (especially people you don't already know) to contact you.
By limiting emails to 500 characters and no attachments, we think its ideal for managing incoming contacts from the public. Everyone with a Twitter account has a Shortmail account, email@example.com. You can claim your account at Shortmail.com
