Love the concept but hate the name. "iDoneThis" isn't even proper grammar...

This is a case where a few hundred dollars on a good domain name would go a long way.

It’s an excellent name. It’s not supposed to be proper grammar—that’s part of the playfulness of it. It’s not a sentence, it’s a name. What you’re saying is like saying ‘Flickr’ isn’t a word.

It's a stupid name, because it also parses as a sentence, and a wrong sentence at that.

The product seems fine, but the name is irreparably bad.

Maybe I can't see it because the phrase is already in my head buy what exactly is incorrect about "You have got mail?".

Is it just the superfluous 'got'?

Yes. We used to get hundreds of letters from English teachers pointing out that the correct phrasing was "You Have Mail". In fact, at one point, the AOL welcome screen said "You Have Mail", even though the voice still said "You've Got Mail".

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.

Will take a look at it. Thanks! I don't always go up to the www version of blog.* domains and missed the sidebar.
