When you post a topic into these forums, first you have to write the topic title (be brief and descriptive :)) and then
Select the blog you need help with: [dropdown]
everybody has to select this.
However, this information is not shown anywhere, and there are literally thousands of posts saying "We need the address of your blog in question".
Yes, I know the automated bot uses given blog information to determine if the topic is about wp,ORG or wp.COM :-) But us "human helpers" on the forum don't get to see it. And thus, numerous "please give your blog address" questions.
This seems pretty silly...
