NHN corporation has been officially (It may perhaps already... since I'm the one of the NHN, corp.) started to share something w/ exterior developers. Because open source has become the ultimate components, open sourcings are attracting tremendous interest.
NHN DeView is a chance to learn about nhn developer products (zeroboard, cubrid, nForge, ..., etc) from the engineers who built them. The cubrid is a open source database, and nForge is NHN's open source project hosting web site.
This is a good news. However IMO, If they have only value/marketing/strategic-oriented thinking, It'll end in an empty talk.
