Shared Blog / Wiki Capability :)

I was just reviewing a BI blog that was on how to identify and solve some common load problems in the BW.

Was wondering if there isn't some way to collect some of these types of blogs postings so that rather than being splattered across several author's blogs.

Could a moderated shared blog be a possible answer, a wiki? I suppose the author could try to pursue getting it published as an offical "How To", but these are usually a more modest effort.

I think what I'm looking for is a way to collect or index these helpful types of blogs. It might be nice to be able to pull together good forum threads that also serve as reference material.

There are many options with the forum and blog features. Just trying to find a better way that we can "harvest" all the knowledge that's available on SDN, and perhaps elsewhere.

Is it a wiki, is it a shared blog? Would it need to be moderated? Maybe it's something along the lines of a dedicated area like the BW Performance Tuning Knowledge Center on SDN - https://www.sdn.sap.com/sdn/developerareas/bi.sdn?page=bi_performance.htm

Any thoughts? Suggestions?
