ccTLD domains worth it?

I'm a complete newb to domaining. I've seen that there are many decent one word keywords available in various ccTLDs (ie. .im, .mu etc). Would it be worth it at all to snatch up a few of them? If I could get something like hotels.xx or car.xx or vacations.xx etc. I could put WordPress up, some articles and try to rank and sell it.

I'm guessing it would have to be countries that speak English so I know I have a good quality keyword and not some poor translation of what I think is a good keyword for that foreign country?

Thanks for your thoughts.
