It's ironic that the post claims Craigslist cultivates an exaggerated image of doing public good, but then repeats without question Padmapper's claim that it's all about doing more good and saving people time.
I strongly suspect both sites are pretty equal in their overstated desire to "just do good".
That's not the only motivating factor, it's more complicated than that (not wanting to see something I've worked on for a few years become less useful, for example), but it was the main one in starting PadMapper, and the main one in deciding to do this. He was saying that CL's actions seem to contradict that mission.
I'm not saying that. Like any person, I'm more than 2D and have a whole bunch of motivations, but unlike most companies, making oodles of money isn't my main one for this, and so I don't prioritize it very much when it conflicts with other things. I find doing things that solve problems for people interesting and fulfilling, and that's primarily what motivated the creation of this.
