I think it would be cool to, along with posting blogs, post video blogs where blog writers can make videos about how to make games or showing off cool aspects of Roblox.
I think some video tutorials would be great! There could possibly some tutorials on GUI manipulation with a bit of scripting involved.
Personally, I'd love to see a video/text tutorial on how to make use of some useful web APIs with HttpService that can be implemented into a game (E.G. Discord, Trello, Google Analytics, etc.)
