In summary it's extremely hard work, time consuming and frustrating with the end result of eventually getting some premium domain others will want. But it may not be worth the trouble. If you try it with most or all new extensions, it will be a full time job with overtime, no pay or benefits and an increase in grey hair. I recommend only fart around with a few extensions you are interested in, perhaps one to five.

A message to frustrated ".com" domainers.
Lesson 1: I do not buy ".com" domain names;
Lesson 2: if you work in the domain name business, you use a domain name ending in ".domains", not ".com";
Lesson 3: I only answer emails ending in ".email", other endings won't be read;
Lesson 4: in regard to domaining, I only visit websites ending in ".domains";
Lesson 5: all this is a joke, I don't buy domain names ;-)
