Many of us used to offer suggestions and tips to those who posted the pics, on how to improve their skills. Tips like cleaning up mold lines and ejector pin marks, making sure all four wheels touched the ground, etc. But too many folks took these comments as personal attack, so many of us are now reticent to offer any comments at all.
The other part of it, for me at least, has to do with the subject matter. I look for things I haven't seen before. When I see something that I consider creative and unique, something that catches my eye, then I'll comment on it. I have to admit that lowered suspensions bore me to death. Instead of taking a '63 Chevy and "slammin it inta tha weedz" why not build it as a '70s dirt track racer or show car? Maybe build one based on how you think a 2009 Chevy will look when somebody does a customization on it in 2042? It's just not easy for me to say "Ooooh lookie, another low rider!" and truly be excited about it.
