DZone seems to be more geared towards programmers/developers than simple web designers.

With that in mind, I love DZone and go there far more than any other social bookmarking site. The rest are just a pot luck mix of crap, while at DZone I know I'll get stuff that I'm interested in.

So if you can get it going, then I think there's surely some traffic to be made. Niche bookmarking sites are far better in my opinion than general ones... but the problem is you need to get a critical mass of traffic before they get to be useful.
