Update (based on last Saturday's Trust data dump):
This has grown to 4.6 GB of data.

On my Trust list, I include 19 users on Depth 0, 159 on Depth 1 and 443 on Depth 2. There are even more on Depth 3 and 4, but I don't use see those with default (Trust depth 2) settings.
On Depth 1 already, I don't recognize all usernames. My exclusions on Depth 1 include many users who's judgement I don't necessarily distrust. On Depth 2, I don't recognize the majority of the 2003 excluded users.
