Hey,sorry if its silly to ask ,but.. what is this blog? It says is official AND made by fans;I am really intrigued,is it really going to be an act 8?

This is Officially the blog of a Homestuck fan project called Act 8, which picks up from the end of canon Act 7, and continues from there. It’s intended to be mostly canon compliant, but is not affiliated or sanctioned in any way with/by Andrew Hussie or What Pumpkin Studios. You can find out more about the project by reading our About page, and/or our FAQ.

Basically, it is indeed meant to be a complete final Act of Homestuck, with development spanning approximately 1 year, but it’s made by fans, just for fun :o)
