It is a pretty compelling argument for little benefit on Yahoo's part. The correct answer for Yahoo is to freeze email in the previous domain, create a new domain for mail and move forward. But there is a certain lack of understanding that is settling in a Yahoo which feels distinctly like 'new young people' (and I mean that in the nicest way possible) but people who consider the time before they were aware of the world "ancient history" and for new grads from college in 2012 - 2013 that was anything before 2000.
Imagine the fun that could be had if Hollywood decided to 're-use' old stage names. We could get a bunch of new John Wayne movies!
Looking at it, fuck, I dont think you really link baited enough.

I can almost no benefit to this.

Okay, who are you and why all of a sudden are you popping up in news aggregators like Techmeme?
Sorry if I missed out on some new (or old...I have no idea) thing here, but I've never heard of you nor your site. Is this suppose to be some alternate blog/identity for some other semi-famous tech writer or something?
Again, I apologize for not being hip or "with it" in regards to who you are. But you tend to obscure who you are on both your site and twitter feed. Why?
