It's an extremely rare day that I don't take a look at Slashdot, and recently it's been the same with Digg. And I've recently noticed an interesting trend between the two sites. For the past several days, a number of the stories that made the front page of Slashdot were previously reported on at Digg (in some cases, several days earlier). I find it interesting that the democratic approach of Digg results in faster story publishing than the moderated format of Slashdot. But this process comes at a price. A larger number of duplicate and "junk" stories appear at Digg than at Slashdot (although the latter isn't without its share of problems). And Slashdot seems to carry more technical articles than Digg (it is, afterall, a techy news site).
I have seen some discussion recently about whether or not Digg will replace Slashdot. Personally, I don't see that happening. Too much is broken at Digg. You can't set many personal options, duplicate and "junk" stories are too plentiful, and new content seems to take longer to rotate through the system. I enjoy both sites (although I read them with a grain of salt), and I think both will be around for a long time. Fortunately, they complement one another nicely, and that couldn't by any nicer for the geeky crowd.
