Both the IETF and the W3C are meeting in Japan this month. The W3C TPAC meeting was going on this week in Sapporo, and the IETF meeting is beginning next week here in Yokohama. Given the proximity of the gatherings and the technical topics, many people are attending both. This was the first visit to the W3C for some of us, and we wanted to share our experiences and point out important work that crosses organisations. You may remember that to increase cross-pollination, both organisations had made an offer for reduced registration fees for new participants from the other meeting. Here are our experiences: http://www.ietf.org/blog/2015/10/visiting-the-w3c-meeting/ Jari Arkko, with Barry Leiba, Ari Keränen, Heather Flanagan, Karen O’Donoghue
