The proposed format of GBeers events is one hour of lightning talks (with each talk lasting 5-10 minutes. Ed.) on unrestricted topics every month, with the talks possibly being recorded for internet distribution. A further possibility is for virtual GBeers through Skype or Google hang-outs.
GBeers have so far been organised in Madrid, Las Palmas, A Coruña, Seville (all Spain), Chicago (USA) and Lima (Peru). Further information about this initiative can be found on the GNOME Live Wiki.
