Even though I am new to the xenForo community, I have been a web developer for over 16 years. I am so excited about this product and the opportunities this community represents.
The Have You Seen...? tutorials are excellent ways to learn about the various parts of the system. Would you consider a broader overview video that walks through the system at a high-level? I have dabbled with plugins on other systems (phpBB and vB) but want to get a better understanding of the framework. (things like the dispatcher, router, controller, etc. and how they all interact) Maybe have a general introductory video, with follow up tutorials on each area with a more in-depth discussion on them.
I think xenForo can quickly catch up to many of the competitors if the community can develop solid AddOns that compliment the core product. (like many of the examples that Jaxel, Shadab and others have developed) It's amazing to see what has happened in such a short time period...
I would love to hear Kier's insights on the approaches the team there has taken and ways they have implemented the platform that they find particularly interesting. I realize everyone is busy coding and getting the product launched, but these tutorials have been refreshing and very informative.
