Is there a tagged Q&A engine similar to Toster?

Question

CMS

Is there an engine similar to Toaster? To also support tags, authorization through social networks, search for already asked questions when writing a new one. After all, they posted the livestreet habr engine, why not lay out the toster engine? After livestreet was posted, a lot of good habra-like sites appeared, but on a different topic. I personally saw one about cars and one about coffee. After all, everyone wins in the end.

Answer 1

I'll subscribe, the question is waiting for an interesting one :D

livestreet is not a habr engine. It's just that the first versions were with a design similar to the habr of that time.
And why do we need some kind of engines? Take a framework and write whatever you want.
