I upvoted it, though I feel the pain on getting upvotes and reads on here. I think the last article I wrote got more upvotes on Lobsters than here. You gotta get just the right title at the right time, or it slides off the front page before anybody sees it.

I'm not sure what the best way to get going is. A webmail service dedicated to it would get the best UI, but there's the overhead of getting a webmail service with competitive features to Gmail, Yahoo, etc going and keeping it running. Or you could do a plugin or something, where it might be a challenge to put together a good UI and keep it in sync with Gmail's updates.
