Contrasting the DC14 KSP keyring[0] from roughly the start of DebConf (and thus before the keysigning party) against roughly a month later, there has been a change in ranking of the top 5 "connectors":
[20140821] 1872: Stefano Zacchiroli (4900 707D DC5C 07F2 DECB 0283 9C31 503C 6D86 6396) 1240: Daniel Kahn Gillmor (0EE5 BE97 9282 D80B 9F75 40F1 CCD2 ED94 D217 39E9) 647: Anibal Monsalve Salazar (C604 5C81 3887 B77C 2DFF 97A5 7C56 ACFE 9478 97D8) 558: Stefano Rivera (8B5B D33F 542B C3FC 03D5 5A9A 5110 6DF5 CD92 D072) 494: Jonathan McDowell (0E3A 94C3 E830 02DA B88C CA16 94FA 372B 2DA8 B985) [20140921] 2475: Stefano Zacchiroli (4900 707D DC5C 07F2 DECB 0283 9C31 503C 6D86 6396) 1422: Daniel Kahn Gillmor (0EE5 BE97 9282 D80B 9F75 40F1 CCD2 ED94 D217 39E9) 499: Stefano Rivera (8B5B D33F 542B C3FC 03D5 5A9A 5110 6DF5 CD92 D072) 387: Jonathan McDowell (0E3A 94C3 E830 02DA B88C CA16 94FA 372B 2DA8 B985) 300: Paul Tagliamonte (8F04 9AD8 2C92 066C 7352 D28A 7B58 5B30 807C 2A87) There has also been net increase in largest-component connectivity: connectivity strong connectivity August 95 87 September 113 105 The reduction in total number of valid keys from 123 to 122 represents one key being revoked in the September data. A side effect of this is that the arbitrary key identifiers from 97 on up refer to different keys between the two months. 96 and lower are constant.
