It seems like everyweek there's a new one. What I'm wondering is: 1. Is it worth anything to get these TLD's if the domain name is good? 2. If I am planning on having a site that is medium size (a thousand visitors a day), is it worth it to get more than just the .com? How about mispellings or putting a hyphen in between words etc?
Regarding 2. I think it can be worthwhile buying more than just the .com, i plan to do this for a few of my projects, and for at least one i will purchase the misspelling too. I think it can depend on the site your working on and how strongly you feel about investing in the extra domains.
The problem is it's a slippery slope....there are literally dozens of names I'd have to buy to buy all of the TLDs. And then alternate spellings would multiply that.
