One thing that I liked with the old site was that when I released a new version of BigIPReport the article ended up at the top. As it is now I feel it's harder for people to find the project and releasing a new version kind of gets forgotten amongst the old articles.
If you want a thriving Code Share I'd propose that updating an article sends it to the top of the list. It'd also make sense to me to separate code contributions to Crowd sources technical articles as they are two fundamentally different beasts. If I want to find new cool/helpful tools it would not make sense to sift through BigIQ How-to's to find what I am looking for.
