All your Snail.io are belong to us
And by "us", I mean "me", Josh (of joshtronic.com).
You see, I happened upon this domain a while back. It happened to be close to being available. I also happened to pick it up once became available.
I'm sorry if you were expecting another site all together. In fact, I actually couldn't find any information on what the site was before I grabbed the domain.
I've even talked to some folks, and nobody seems to remember what the site used to be. The Internet Archive Wayback Machine wasn't much help either.
I have my speculation as to what the domain used to serve, but everything thus far is a theory at best.
If you have any details about Snail.io, please get in touch.
