Annoying the fuck out of people is a good way to chase them away.

Blogs work as much via reblogging and word-of-mouth as anything else.

The most egregious example I can think of is the Google Blogger dynamic designs, which I find both completely frustrate any attempt to read the content presented, and which I've yet to find a way to un-do the damage via local CSS.

In most cases, even Readability curls up in a corner and weeps quietly rather than present its exceptionally clean and quite preferable page design.

I've appealed directly to several blog owners to chose a different site design (e.g., not the "dynamic* layouts). Generally, I close the page as soon as I open it.
