Zipdrive, I've just signed up today for Buzzle and I'm waiting for them to approve my author status (can take up to 4 weeks, they say). From what I saw on their website, they approve high rated content, not so much link building articles which you get for a few bucks on various content writing sites like The Content Authority. But this doesn't scare me, I'll try and see if it works, as I feel the need for a few strong article directories besides ezinearticles, goarticles, hubpages and infobarrel, which I currently use.
Buzzle is one of the best sites for article marketing, right up there close with ezine, hubs, and infobarrel. Good indexing and juice, but they require higher quality, informative and unique articles. Plus, I think they suggest at least 600 words.
Buzzle is a high PR , do follow article submission site. You just need to comply on their qualification in order to accept accept your articles there.Read this: http://www.buzzle.com/terms.asp
I use Buzzle and find it a great article directory. Mybuzzle articles get 10x more traffic than my ezine ones within the 1st week alone.
