I was going to come up with one of those clever top 10 lists but when I went to the SpringOne/2GX home page, I saw 10 great reasons to attend staring me in the face.
The early bird discount ends Friday, September 18th, but even at full price this event is less expensive than JavaOne and will contain way more good technical content. Check out the rest of the speakers and the awesome session list at http://springone2gx.com
If you're interested in Groovy, Grails, Griffon, (or related technologies) or if you use Spring in any of it's myriad forms, or, for that matter, if you use Java, you won't want to miss this conference!
See you there!
