I designed pug.io to be a tool to invite in-game friends to meet up with you. Post the link while you are afk, and when you return, expect people to join you based on replies. pug.io does not link your in-game name back to your actual name, since it exists to connect people on the internet who you would not send e.g. a facebook invite, given you are not going to be facebook friends with most of these people.
I sent pug.io around to a few friends. Based on feedback and usage, I can say:
The instant signup works as intended. pug.io has very low friction for usage once someone visits the page.
My friends are not interested in meeting people in game (League of Legends). Not really, anyway.
Otherwise, people agree that the idea is neat.
Since my alpha users are not really using it, the project has a dim future. I have a lot of ideas on how to make it a really great tool. Given the data model, pug.io can learn your social network of in-game friends and friends of friends based on who replies to posted games. Then it could show you a list of upcoming game proposals based on that network, and even notify you using email, SMS, or some other push. Further features would enable you to meet others in pug.io itself, especially when you realize that someone in your League network plays another game you really like.
It's possible that those features would get people using it more often, but since there's very little usage with the core feature, I am not sure that they would. Perhaps my alpha users are not representative of who wants this feature. (I think that they are.) Perhaps I need to market it and get the word out. (I don't think that would solve anything.)
pug.io will stay online for a while. My monthly expenses to keep it running are negligible for now. We will see if anyone sends feedback that would clarify the direction of the project. pug.io is currently hard-coded to League of Legends, but supporting every game with a type-ahead list of games is less than a day's work.
