Uh Oh. Seems Tuesday night at ad:tech San Francisco is getting crowded party-wise. Luckily a couple early events are right in the Moscone (West) center and the others aren’t too far away. Adding to the Affiliate Summit Beer Garden, ad:tech SFAMA Mixer, Digital Social Media Networking and Oldtimers Foundation parties is the Advertising 2.0 (oh, please) Party which will be he;d at the W hotel.
