The one site of me that got hit has got, besides a lot of content, a photo gallery as well. Each thumbnail is going to a seperate html page (without ads) to show a big version of the picture.
Could it be that G sees these as thin-content pages?
Would it be a good idea to remove them, even though my visitors like them (lots of comments)?
My entire site is a photo gallery along the lines you describe, with a separate page (with ads, in my case) for each image. The images have captions but few are longer than 100 words. As I've mentioned before, my traffic is up at least 10% since the update.
I don't think it's as simple as measuring the number of pages on the site with little text on them, or as simple as measuring bounce rates.
My current theory is that they've found some clever way to measure user first impressions.
