I was shocked when I read of your leaving. I've posted very little in my years on FR, but have depended on FR for the best conservative insight into the news, and yes, I've noticed a change in the atmosphere here. Your posts, as others have said, have always made me stop and think and somtimes laugh out loud. I'll sorely miss your insight and wit. Please, consider starting your own blog (and let us know the address) so we can all still tune into your world view.
When some of the FR 'big names' began to leave I wrote it off as normal come and go, but if you go Ivan, I will have to reevaluate. I second the idea of a blog.
