Wes and Steve are two of the sharpest and nicest guys I have ever met in this industry. They created something with Tracking202 that has become the de facto standard in this industry for tracking. Sure, some of you ballers have your own tracking systems built out, but the majority do not. The open source version of 202 allowed anyone to build in the changes they wanted to have on an already-tested framework, and millions upon millions of dollars of traffic have been run through the 202 platform.
Was it a mistake to sell out to Bloosky? Probably. But in business you take gambles sometimes, and sometimes they don't pay off. I for one am super glad that Wes and Steve have the platform back, and I would be extremely surprised if they go off and sell it again.
The value of what they created in 202 was not just the tracking platform, but also the culture that they built up around it. If you were a 202 user, you had access to support through their Meetup202 groups, often to Wes and Steve directly through their forums or even AIM, and a network of thousands of other affiliates that were using the same platform and could help you through it.
They obviously were on to something because since they sold 202 to Bloosky there have been a bunch of new tracking platforms popping up everywhere (Lambda Tracker, Bevo Media, w3roi, etc). Affiliates did feel slightly betrayed by the sale and didn't feel comfortable with Bloosky, but they still wanted that 202 feeling.
Now that Wes and Steve are back, the ball is 100% in their court. I personally have no doubt that they are going to bust their asses to win back the goodwill of the affiliate community and most likely will work on a Tracking202 upgrade that will blow everything else away. 1.5.1 was just a bandaid upgrade with a few tweaks (and a heavily-rumored Bloosky spy script). Whatever version is coming next will be the true successor to 1.3.2 and I can't wait to see what it is.
Anyone that says that 202 will never be what it was before is correct: it can't be the same, it will either be better or worse than before. I'm putting my money on better.
