Skype with Diego about geometry; email with Vanderlei about filtering; iChat with Susanna about school; Jabber with Spadim about temperature control; Facebook with Katrine about travel plans; Twitter with @jdborges about newspapers; RSS with Gabriella about the meltdown; Safari to read the papers; Camino to erase junk filtered by Gmail; talking of email, 70 non-junk stored in the last 2 days; now Firefox to post on blogspot.
