I'm considering getting some typo domains but not sure about it... First of all I want to avoid legal issues (by the way, how MS don't say anything about hotmali.com ?), so I won't go with the "NASDAQ-100" companies, besides they all took. But considering getting some medium traffic domains. What do you think ? Sorry for my bad english...
you should pay attention to not show their tm in you ads. If you use adsense or if you park it you can easily have problems.
They are ok for parking. Be careful with trademarks though from certain companies, eg microsoft. I have a few but will be selling them off. My main aim is development and there's no way I'd even consider developing a typo domain, too unprofessional.
