The site is really much better now, and one can quickly see what it's all about (whereas before that was only understandable for spec addicts, and that only after due studying the site).

	RE: JDO 2.1 specification draft can be reviewed... by Robert Greene :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I think if we're going to put a story on the serverside, we ought to revisit some of the content of the site. For example, "Why JDO" still refers to J2EE Entity Beans, Toplink, Hibernate, etc. Perhaps it is time to update to address JPA and put a statement in place about how JDO fits in with how alternatives have evolved over the last 3 years.

	oops RE: JDO 2.1 specification draft can be reviewed... by Robert Greene :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message I believe I've miss spoke. There has been a lot of work done on the site, great job Andy. At first I thought it was a cut and paste of material, when reading the "Why JDO" page. Quite possible that's the only spot that needs updating. Cheers, -Robert Robert Charles Greene V.P.
