They are very distracting. The sponsored links between posts didn't bother me at all, but this is just way too much in the body of a post.

I suspect it was intentional. I had trouble replying to posts for about 30 minutes today. After I got in again I noticed the ads in the body of a post.

I really support FT, and would even pay for it, but I think these ads are just a bit too much.
