You have some very nice Mobis in your signature but my advice to you is slow down on the buying. Do research, make lists of open names, don't worry about being beaten to the reg unless it something outstanding that appears to be missed. Then take your open list and do research on Overture and WordTracker to see how often a search term is searched for and then Google to see how many people are advertising for that keyword. DON'T BE IN A HURRY.The money you save by slowing down and targeting will way outweigh the names lost to other people regging.
These recent regs are just way too early IMO. I could be wrong as I've seen some spectacular MOBI sales on names that names I'd never reg.
That said I'll say it again that you've got great MOBIs in your sig. I'm sorry if this isn't helpful or seems insulting. I am only trying to help as I use to reg anything and everything because I was worried it wouldn't be there the next day. There is nothing worse than watching mediocre names not sell and then having to decide whether to renew or drop. Believe me I've made tons of mistakes and I am only trying to help you understand how to avoid the same mistakes I made.
I still am regging Mobis but I might spend 4 hours building a list of open names and then comparing them for potential revenue before I decide to reg the better ones. I never reg all of them on my list. Only the ones that stand out as I might find something better open tomorrow.
Also if you can afford to reg many Mobis I recommend investing in a Cell phone and an internet plan and start mobile surfing. It will help you to understand the complexities and special needs of mobile search. It will also help you think about what people will be looking for in a mobile environment.
Quality over quantity always wins
Best of luck to you in your domain research!
