It is a good question, but first you must decide your reason for buying.
Are you lookng for a long term investment or short them investment?
Are you looking for a quick "filp" to generate some extra cash?
Are you looking to develop?
Are you looking to drive traffic to a specific website?
Are you looking to park the domain and generate parking income off of type in traffic?
There are some on this forum that do one of the above and there are some that do all of the above and I am sure there are a lot more reasons than the ones I have listed above.
After you have answered that question than the best thing to do is stick to an area that you know, and then research, research, and more research. This forum is a great place to start.
