Why is my post not in the New Posts list?

A more accurate title for the new posts button would be new and unread posts. Every time you hit the new posts button, the forum essentially does a custom search to generate a list of topics that have posts you haven't read in.

You've already read your thread - which is why if you go to the Nexus One section the title won't be in bold for you like other threads and why you don't see it under new posts. But for me and everyone else, your posts will show up in that list

You can see what I mean if you read a thread from the new posts list. If you read something, it won't show next time you generate the list. (Although keep in mind refreshing the page is not going to regenerate the list, you have to click the new posts button to do that).
