geeks prefer with ORG! if I want to build a forum or community, maybe I will choose ORG!
but personally I love .biz, because its related with biz stuff! e.g forex, stocks, loans, and etc! but for ecommerce, or online store, or for company! com, should be your priority! so I am not surprised if some people will spend more money with com! because If I have company and promote on national TV, for sure,
I don't choose dot net, ORG, or even Biz! because I don't want some people get benefit from my tv ads!
Imagine if I buy dot net! mycompany dot net, and promote using TV ads, millions ppl watch! and they type dot com extension! for sure, I will pist of! unless, for domain name hack! it could be different! for example, Pay US! or pay.us! or maybe author.co! or maybe jobs in us or Jobs.us! or maybe remember us (remember.us) I have no worry about it! though, just to safe, I will buy all extension!
personally I don't like COm that much! though, the number tell different! so, I will admit, com are the king! ORG for Geeks, Biz, or biz stuff, Info for information, etc and etc!
