The alliteration thread is just too lame, and will cut down on the frequency of posts here. Here is my suggestion for today's theme:
For today, this thread can become a metathread.
That's right, a thread about other threads. This would stay close to the thread's overall goal of being a thread about nothing. It would also give us a logical edge over ANY thread that wished to surpass this one for number of posts. As soon as another thread receives a post, we post about that thread.
If worse comes to worse, we can talk about dogs or cats (or lizards ... sorry EarlJam).
