The ads are because Yahoo's been shafting us this whole time and so these are trying to.. reverse that trend.
I have to say I absolutely LOVE the massive, obtrusive ads we now have on the site!
And of course, the no-author-shown-on-viewnewposts is absolutely amazing too!
The author thingy is IPS's fault. There's a bug report about someone complaining about it too so we're trying to switch to this thing that LW found.
