Interesting thread. I also read all those articles and came to the conclusion that I had to merge together thin pages (that had lost ranking) for my main website (7 years old, PR6).
I did this two days ago. About 20 pages total that were once ranking top 20, but had lost ranking after the update.
I checked them again tonight and... They had lost even more ranking after being merged together.
I took thin pages and combined them with related pages to make longer ones, then dumped the ones that never had good ranking.
Went from bad to worse.
I'm not changing them back. They were quality to begin with, just short because all that could be said was said.
