Have you noticed that Iris has been acting up lately, feed jumping up and down, and reloading, while you're trying to read? Especially on global. It does for me (I'm using Firefox).
Also, I see in NoScript that it has started to try to run script from Google (gstatic).
Snort also uses Google IIRC, and Coracle doesn't show all notes from the people I follow, despite having the same relay list there as on Iris.
Anyone have any recommendation on a working, Google-free web-based client?
