Good example of business blogging

OK, so blogging is cool and makes us all feel warm and fuzzy inside, but can you really use it for business?

Here’s one REALLY good example I found on businessweekOnline, Ice.com, a jewerly manufacturer, that has created 3 different blog Web sites:

http://www.justaskleslie.com/ “just ask Leslie”, apparently some heavy-duty jewelry chick that gives people advice on what to buy.

http://blog.ice.com/ a “corporate” blog that tells the whole world about their great accomplishments

http://www.sparklelikethestars.com/ “Sparkle Like the Stars”, a blog that covers what kind of Jewelry the celebs are wearing.

Very cool, very simple ideas here. Both justaskleslie and sparklelikethestars of course link EACH product to Ice.com.

I think we have a pretty good example of a great blog business model here. WhatChuAllTink? Post your comments please!
