I put a few on Ignore during the Presidential election. It's a lovely feature. I think I've taken them all off Ignore now. Outside that time frame, they have been worth reading and I was always clicking on their posts anyway.
In the format of this forum, it's easy enough to skip over posts that have become heated and off topic. Also, over time you learn certain people are very passionate about certain topics. If you are not in a mood to read that, just skip it.
