If you have more than 100 follows or unfollows since the previous check, Joule displays "Many" instead of the names, and links to this post. (This used to be "Hiccup".) The three reasons for this are:
- We have to do a separate lookup in Twitter for every userid we haven't seen before, to get the icon and username. For 5000 changes in a day, that slows page load times a lot. This is still a problem.
- There is an old pre-Twitter assumption that 100 follows or unfollows means either that Joule broke, or that LJ broke when it sent us the names. Clearly this is outdated.
- There isn't enough space in the chart for more than a few hundred names a day without making the page insanely long.
