There's plenty of books I've read, given the big oh, spare me! and discarded. But I've never regretted reading a book, whether I liked it or not.

Just like there's plenty of Mudcat threads I've opened, looked over and closed REAL fast. I've never regretted that either. But I have regretted failing to close them, and adding my two cents worth instead. Some things aren't even worth the energy it takes to ignore.
