dont say we never help...
here's a list of what i considered the best few in CS over the years.
hope i dont get any flame for this, or maybe i'm been spoon feeding too much...
under the various sections, go look for them there...
wedding portfolios, jOhO (look at his webby for videos and photos together, has very nice b&w photos).
world of nature, raptor84 (has a huge collections of pets portraits in his flickr account).
land/city-scapes and travel, zoossh and night86mare(for hrd shots), both of them seems to travel to quite a no of places.
night photography, Hosea (master horse shoots a lot in the wee hours of the night) and Stanly, both of them have good exposure skills with night shots.
feel free to add if anyone else deserves to be in the list.
