With regards to Twitter specifically, that username is essentially being squatted as it hasn't been used in over 6 months. Since writing the original post, I have learned that Twitter is supposed to be deleting all accounts that haven't been used in 6+ months. They also do have a process for trademark holders to contact them about existing userids, so I'll pursue that avenue.

Twitter names specifically are used with an @. Since I already own the domain name, it'd be very confusing if I didn't have the twitter userid, especially since twitter clients will automatically convert domain names into twitter usernames.

Personally I don't think it has anything to do with poor versus money. I'm not rich, but I happen to have a trademark and did due diligence when registering the company name and domain name, such that no one else was using the combination of those two words on the net. I'd like to continue investing in the brand and eventually it might make perfect sense for someone to infringe purposefully. I've already had a few threats over the past year from a couple of whack jobs.

I also have no problem with companies buying names if those happen to be of the more generic variety and someone else is already using them for non-infringing purposes.

Incidentally, the "Twisting my melon" line can be attributed to Steve McQueen (circa 1965), likely where the Monday's got their inspiration. I covered this on my site back in 2006 when a few people asked. But while the company name is inspired by this saying, it's distinctively different. I've been using the domain since 2000, with the current company launched in early 2006.
