Based on a helpful recommendation, I've decided to start posting some of my novice questions about Gosu on StackExchange.

I posted a question and tagged it with "libgosu", "ruby", and "2d-games". I tried to tag it with "chingu" as well, but it appears that no Chingu tag exists, and I have nowhere near the necessary reputation to add a new tag. Would someone who has more reputation than I perhaps see fit to add a "chingu" tag on StackOverflow?

Also, in case anyone wants to help answer my question, it is located here. I plan to post more Gosu and Chingu related questions on StackOverflow in upcoming days/weeks/months.

EDIT: I also asked this additional question.

After some more digging around, I found a StackExchange site dedicated to Game Development. I went ahead and posted one of my questions there, and I got several responses within 24 hours. Additionally, someone who read my question immediately added both "libgosu" and "chingu" as tags.

Going forward I will be posting my Gosu and Chingu related questions on gamedev.stackexchange.com, where it seems that questions are less likely to turn into "tumbleweeds".

I think this is a really good resource, which may be of benefit to other Ruby/Gosu novices like myself.
