Why Devs? Why?

So first and foremost, it is really important for me to stress how much I personally and im sure the community appreciates all the hard work devs and dev teams put forth so we may enjoy and open and awesome android. That being said there is an almost universally adopted behavior that truly baffles me and I truly wonder about it hence this thread. Why do devs spend so much time and effort to create truly amazing roms only to post them without any screenshots? This is not me being lazy and im fully aware that if i was to flash the rom i could explore it to my heart's content but seeing as to how it takes 20-25 minutes to nandroid backup, wipe, flash, setup ect only to find a rom too bloated or slim on features. Sigh... what im trying to say is I (im sure im not alone) often skip roms without screenshots and favor ones that give me a brief preview of what im about to flash. Thoughts? Comments? Concerns? Am I overlooking something obvious or are there others who feel this way?
