A Packed Conference Hall
To me, a packed JavaOne conference hall during the keynote address this morning proves continuing and very broad enthusiasm for Java.
Read Calvin Austin's very succinct report for the full keynote. (One more highlight was Jeff Jackson's announcement of Open Java EE.)
After the keynote, I rushed to another presentation I was waiting to attend this morning — There were long lines of folks waiting to get into Dave Johnson's presentation on a REST-full implementation of HTTP server and client for the ATOM protocol.
