Something I think about occasionally, that doesn't keep me up at night by any means, but I still find curious: When I upload photos to Flickr, they are noticeably less sharp and detailed than when I look at them in Lightroom (or Photoshop, or On1, or...). I figured there was some sort of compression or something going on during uploading, some compromising of the file, so I downloaded an image file from Flickr and viewed it in Photoshop, and all of the muddy fuzziness is gone - it's just as crisp as when I view the JPEG in any editing program on my computers.
Here's an example, a screen grab of two windows I had open on my desktop: Left - the image in Photoshop, and Right - the image as seen on Flickr.

What gives? Where does all the crispness go? I have uploaded images at different DPIs, with different sharpening levels, and viewed Flickr in multiple browsers, but I haven't been able to resolve it. (Ha!) Does anyone else notice the same thing?
