Where [else] do YOU go for photography tips, discussion?

As much as I would love for The Lens Forum on The Verge to be a compendium for photography knowledge, there are numerous resources available online today with a wider user base and/or longer-standing community and/or a resident expert's archives of posts. I'll list a few that I've referenced and have been useful or helpful to me in the past few years but would love additional input:

(in no particular order)

- Thom Hogan - for all things Nikon

- Flickr groups discussion - for specific topics; some groups are more active than others

- r/photography on Reddit

- Fred Miranda fora

- Digital Photography School blog and fora

- Light Stalking

- Improve Photography

- Ken Rockwell - sometimes more opinion than fact or usefulness, but his site was my introduction to photography
