My thoughts: Do you have even one person who is using the site? - If yes, get a quote from them. Show us their pictures. Social proof makes it easier for us to trust the site. - If no, talk to friends, refine the idea. Get 10 (ideally 100) on the site. Ask them why they are using it, and change the phrasing on the site appropriately.

Personally, I can't imagine needing to Archive a repo. Yes, repos get old, but that's what a source repo is for. If you can give me reasons, then I might signup.

Now, maybe you are: 1. offering me a way to save money because GitHub charges per repo. If so, tell that on your homepage. 2. offering me a way to save time by not having to see junk. If so, tell that on your homepage.
