Just recently there was a guy on the NANOG List ranting about Anubis being the wrong approach and people should just cache properly then their servers would handle thousands of users and the bots wouldn't matter. Anyone who puts git online has no-one to blame but themselves, e-commerce should just be made cacheable etc. Seemed a bit idealistic, a bit detached from the current reality.

Ah found it, here

Brodie interviewed the creator of Anubis a little while back, it's pretty good.

I had seen that prompt, but never searched about it. I found it a little annoying, mostly because I didn't know what it was for, but now I won't mind. I hope more solutions are developed :D

Fantastic article! Makes me less afraid to host a website with this potential solution
