Why I register so many domains?
This is a question I get asked many time. Everyone says that register 1 domain name then work on it to get it pull large number of audience/ visitors/ reader or whatever you call it. I ask if you don't know what you are going to do if you don't get the kind of success you want then what will you do? My guess is your answer will be “start again” and what if you wont get such nice domain at that time what you are getting today than? And what about the lost time you have wasted in your “one blog” strategy?
My suggestion is, Start multiple blogs at one time, try to find out with which one you feel comfortable and when you find the success you were looking for in one or two blog than abandon all others keeping 1 or 2 most successful ones.
