Very true, not to mention the S/N ratio of Digg and Slashdot traffic (especially Digg traffic) is really pretty horrible.
My personal experience (3 slashdottings about 5 years ago, 2 diggs and a techcrunch in the last year) are that those traffic spikes have very few nuggets of valuable hits in them.
explain. It's better than a sharp stick in the eye, right?
Agreed. I think it's unrealistic to hope that level of traffic from the first 2 days of being on slashdot and digg would continue. And it's clearly a good thing that our new company blog got lots of exposure. So I'd greatly prefer a sharkfin to a flatline. Especially since, as swombat suggested, we have been getting residual traffic as well.
