What Type Of Domain Extensions Fits My Blog?

These are the questions, bloggers ask themselves when purchasing a domain name, there are so many domain extensions out there, ranging from the top tlds to the least ones, examples are; .com, .net, .org, .co, .biz, .info, .edu and even country generic tlds like; .com.ng, .ng, .us, .co.uk, all this are domain extensions, so the question is "which one fits my blog", these days bloggers buy domains names according to their pockets, some even use .me tld for a blog, .me tld is fits for a personal/profile website, something like ifeanyionuegbu.me, the domain itself will tell that it is about somebody, without wasting much of your time, i would like to tell you what this tlds means, starting with .com = this domain name means commercial, that means anybody using this tld have a business and wants to make money/profits, .net = this tld stands for network, somehow they don't want make money, .org = this tld is the short form of organisation, websites using this tlds have a company, .edu = this tld is limited to educational institutes, such as schools, universities etc.

For you running a blog, the best tld you can go for is .com, a second choice would be .biz (as it also stands for business), how about country-generic tlds, as you are living in nigeria, and your pocket can't buy .com, why not try .com.ng tld because it is cheaper in nigeria, .com = N3,000 while .com.ng = N1,700, so do the math, how much are you saving? N1,300, think about it yourself
Note:- You will hardly have visitors from other countries
So that's the disadvantage, am not trying to convince you, why not give it a try? and share your testimonies here.
