I never visited craigslist until now, but I think the reason for their continued success is the big userbase, even langpop uses CL as a data source. And you could say they have a super minimalistic design (no pics, just standard link colours and nothing else, although for cologne they have a little de for Germany next their name.So they have design. LWN not so much)
Love Craig's List but hate how painful and ugly it is? Me too. So I made Marketplace. It takes the
pain and ugly out and leaves the good stuff in.
I agree with the other comments that LWN could do with some sprucing up. It doesn't really bother
me that it's currently ugly, I still read (and pay for) it. But I wouldn't mind it being nicer, either, and
it might keep other readers from running in terror.
