I'm having a definitional problem. Does it count as an Instalanche if Instapundit opens up comments and then someone links to me? I've only had five people click on it between 9:15 and 10:30, and since it's an older post I imagine it won't be a huge influx, but you never know. I imagine real Instalanches lead to a much greater traffic increase.
It's already more traffic than I'm getting for that post from the Carnival of the Vanities, but that had a whopping 78 posts in it, and I'm not sure most people looking through it wanted to click on very many posts.
The Humorous Answer:
You will know it when you see it. :-)
The Serious Answer:
When the Great One deems something you wrote worthy of comment, and linkage, in a post on his blog, you can expect just about anyone, from here to the ends of the Earth, interested in the subject, to stop by your place for a look see.
And, that be quite a few folks. :-)
The closest I've ever come is to have a brief e-mail back & forth with the Great One, once, in regards to an essay he wrote on Tech Central Station.
If it's a real Instalanche, you'll know. The one time The New Editor had one, it was over 5.000 hits in a single day.
Good luck.
BTW, I came here because of the Instapundit link.
