Hey, actually you can try our implementation at http://iDoneThis.com (author of the post here). We have a team thing we're rolling out and this post was in part to gauge interest.
This is a case where a few hundred dollars on a good domain name would go a long way.
The product seems fine, but the name is irreparably bad.
Neither was "You've Got Mail."
Is it just the superfluous 'got'?
But, like "idonethis", and like you, we thought our version was just.. stickier. And it stuck.
Downvoter, this was my point: Sticky beats grammar. (See also: Think Different.) Sorry if I was too terse to make it clear.
