I've also tried to create a kind of landing page which would already be able to feature all types of content and also work in the same or similar way for other categories like Resources, Competitions etc.
There's certainly still lots more to fine-tune here in terms of UI, colors etc... so please view it as a quick draft only.
I find the general idea @AlanSh proposed for the resources great:
Add a link (regardless if external or internal, to a blog post etc.) and also a forum discussion to tie it back in and make it clear it's more than a content-aggregate site. The boxes could also be used to highlight relevant forum topics, perhaps even things like anniversaries of interesting historical photographic events (invention of the Cooke Triplet or the well-presented historic photo gear stuff @Maoby creates) as well as relevant photographers, exhibitions etc.
