I think the following statements can be used interchangeably when you want to express Stack Overflow as an address where some post can be posted.

A new question is posted to Stack Overflow every 12 seconds. A new question is posted at Stack Overflow every 12 seconds.

The following syntax expresses it in more specific way using "on", i.e. where a post was posted: e.g. "on StackOverFlow page. or on a Facebook wall.

"posted to", "posted at", "posted on"
