Genome Technology Online has launched another method/technology forum called MethodShare. (www.methodshare.com or http://www.genome-technology.com/forum/index.php)
There are a few articles and some discussion about various life science techniques. But so far, I don't see anything really interesting or different from other general forums such as protocol-online. It is also not necessarily good if you are particularly interested in something for example python in bioinformatics -- you'd better go to more focused places.
Anyway, it is certainly a good e-Marketing strategy. And keep an eye on it!
