So you mean, my post will be in a Roundup, that will coming in Wednesday?
As Trekkie said, the crew submit threads in sections that they are assigned to cover. The final decision is up to the editor(s), and they make the final determination as to which threads are featured in the round up.
In the end remember... its only the internet. We're a huge site with a lot of members but not every thread will gather attention. Sometimes topics take off, sometimes they don't. If you create a thread and you don't get a lot of responses to it, don't take it personal. Maybe the next one will catch more attention or get more of a response.
But starting a new thread complaining about not getting any response is not exactly a way to "win friends and influence people" either.....
