In my experience, finding a quality board has always been topic focused. I.e. if you have a Toyota Corolla and want to communicate about that, just look for Corolla forums, and it'll quickly become obvious if one is lively / your vibe.
Just about to set up a new app to deploy to Heroku, but this does not seem promising. Render seems like the next logical move, but curious where others are looking for alternatives.
It never ceases to amaze me how google search _used_ to work great for stuff like this. You could just type "tbray {obscure term on a blog entry from 10 years ago}" and bam, instant result.
I guess google generates more ad revenue with users forlornly paging through search results, hoping against hope that what they're looking for is there somewhere...
