While it may not be flashy, I personally find the GOES sites extremely useful. Things are often simply placed at obvious and expected URLs, so scraping or monitoring is extremely easy.

I wrote the script that provides the GOES NavSum [1] and it pretty much just builds a standardized text file and drops it in the folder. The neat thing is that this makes it really easy to programmatically scrape and parse the data.

I wrote a personal script at one point that would download the GOES-EAST CONUS image and both EAST and WEST full disk images and composite them into a wallpaper. At one point my server had 500GB of archived GOES imagery. I liked to joke with my former coworkers that I could report image anomalies before they notice because my desktop wallpaper would change every 10 minutes.
