It may be minor to some. But I think its a decient one at best. Especially if one runs a blogging business. Where people pay you to blog about their websites, items, domains etc and what not. Or it can just be a regular blog. But the domain is: blogmywebsite.biz
Of course people will not think .biz will be #1 in the extension area. The first thing that will always come to mind is .com. But if it is marketed in the right way it can bring in some monetary gain. I have seen some who I thought had a great brandable .com name and sold it for pennies. And there was those name that I thought were so so brandable .com names sell in the $x,xxx - $xx,xxx. I have seen even some discussion on what is in the eye of the beholder as well. Anyways.... I digress and what else I need to say needs to go in another forum discussion area. I figure it could have some monetary gain in the future if I ever sell. If I build the business up and have some profits and SEO work for it. I am sure it could sell for the mere reg fee(which was free btw , earned it taking surveys). I was thinking along the lines after building it into a business, could sell for maybe high $xx - to maybe high $xxx.
