I learned not to invent domains, it was painful to invent for NUFFIN.
Now I goto overture, typeie a common word, like sex, game, picture etc, than I check the search munbers, if it's high, that means a lot of people search that word.
Then I typein the search term like sex story, free sex story, etc one by one into register.com to see if any domain with those words are still aviliable.
That's how I find growweed.info, freesexpicture.info etc.
It took me 3 years to get here, but I'll never invent domains again, it's a waste of time and money.
USE goto tools, find most searched keywords and find if there's any good ones left!
Hope this helps.
