I've been reading up a lot on A/B testing lately on HN. Since sequential A/B testing is not recommended due to external factors, I'm just curious as to how someone is suppose to split web traffic (say 50/50 without using hardware to balance).
For those of you that launched a web app, how long did it spend in private beta before official launch? It seems that the general consensus is to just put the product out there to test and iterate. What's your take?
