and i also use the "shitty" script that 1000000 people have, and it works great for me. Its all who you target, at least thats what i have found works best.
and a shitty script to someone might be the worlds best script to someone else, just look at some peoples myspace accounts, hoorible yet they love it, the same goes with anything else, just because its not good to you, does not mean its not good in the eyes of someone else.
Point noted. Any good script can be shitty when in the wrong hands, and on the flip side any shitty script can be gold when put in the hands of the right person. It depends on what you do with it as a webmaster. If you just throw up a default install and hope it becomes the next MiniClip, you're missing something. But if you strive for the unique user experience, then it doesn't matter what script you are using.
