Think about it, if Blockland gets on Steam, more noobs will get on. We already have many noobs infesting our servers, but Steam has many young users.
Also, if Steam lets Blockland on, there will be more and more servers and your-already-popular server will only have 2 or less people on it.
There are a lot of competition for server popularity right now, and it will be VERY TOUGH when Steam has Blockland.
In my opinion, I don't want Blockland to be on Steam.
