Wow, some great discussion on here. The post here definitely is interesting, but it seems to throw out the baby with the bathwater: there are certainly things that A/B testing is good for and bad for, but what are those? And, for the things that A/B testing is bad for, how do you figure out which is which? I wrote an incomplete post on this once that used a restaurant as an example. There are plenty of things that a restaurant can't test with a typical A/B test. Or even worse, if they optimize for local minima (just as the author pointed out), they might be missing some other, longitudinal measure. However, even though some numbers may not be immediately measurable, they're always measurable at some time: it might just be hard to pinpoint a drop in sales or traffic (or not getting the girl) to any single thing. Sometimes you gotta go with your gut, but only after you've analyzed the heck out of the numbers.

Bubbly & Banter #2 This week's edition of Bubbly & Banter features the beautiful, talented, and witty Jennifer Leggio (@mediaphyter and cohost of the Quick-n-Dirty podcast) with hosts Mark Johnson (@philosophygeek) and Julie Crabill (@julzie). Listen in to find out the real reason behind the @mediaphyter moniker. . . Our original topic was going to be centered around the real cost of social media but, as can be expected over a bottle of fine bubbly, we meandered to even more interesting topics. We started talking about cost in terms of maintaining blogs, server space, and time, but then moved into... Continue reading

Bubbly & Banter is a new podcast from Julie Crabill (independent PR consultant) and Mark Johnson (program manager at Bing) focusing on PR, marketing, and product (an extension of our blog project). The idea behind the podcast is that we'll invite a guest onto the show while we all share a bottle of bubbly, because we believe the best conversations happen while imbibing. This is our inaugural episode and therefore guestless. Instead of grilling some poor soul, we talk about our (sordid) history together. Mark was the product guy at Powerset and Julie was the VP at SHIFT, Powerset's PR... Continue reading

Congrats for being at the top. . . but is it necessary a good thing? Perhaps you've missed the controversy about the recent sale of Wellsphere. . .
