These are the questions I ask myself when I think about a recent occurrence. I contacted a developer I found on the Internet regarding the games at their website. I explained that I was looking for links to games, and I let them know that they could submit to my website. I also told them that I would appreciate it if they were to link to me on their website, but it wasn't necessary to do so.
Well, they submitted their games, and they also responded to my email. They told me that they would link to my site, but I would have to pay them to do it. It really didn't bother me that those were their requirements. They didn't want to link to my site, but they would capitalize on the situation and do it if I were to pay for the link. Obviously, I'm not going to pay for the link, but it did make me think about some things.
Currently, I will be spending a couple hundred dollars a year and countless hours of my time maintaining Playpile. I would hope that the site would be useful to some people, but I'm not sure if that could be possible if fellow developers do not support the philosophies behind creating the site. Developers are the lifeblood of the website, and if they don't support it then it will just die. No links to the site, and no submissions means it won't go anywhere.
