Please Review my Website
pedalpete: Start with the good.
1) the site looks really nice and clean
2) your demo clearly demonstrates what can be doneWhat could be improved
1) demo could/should be edited down to just the key features, and really explaining why I would use it rather than going through all the features step-by-step. It's good to have the step-by-step as an instruction, but you haven't made your case of why I would use it
2) login required? Why? you gotta be kinding me?That leads directly to (what I think) is the badI'm not sure you did enough background on defining the need. What problem are you answering. Not to say you haven't found a nice niche market. Very likely you may have, but the way you have structured your site into these distinct buckets of what I own/owned/want to own just doesn't click with me.
Connecting with photos and photographers (I suspect) is less about brand and product than it is about photos. I don't care that this photo was shot on this type of camera vs. that type (you even went down to model level???). 
I would think I would be more interested in knowing how the shot was captured, what makes it special, etc.Furthermore, you've locked it all up so that I can't read the reviews/comments unless I've signed-up, and then it really seems focused on what I would add to my list, which means that you've locked out the biggest benefit which is the opportunity for discovery.I'm not a shutterbug, so maybe I don't understand how camera officianados think,but I am a person, and something feels very wrong about your approach.
