If companies can be compared to living beings, then the code used to run them is their DNA. John Gruber of Daring Fireball asks a very pertinent question of the rumored and now supposedly dead talks for Microsoft to buy Yahoo! what exactly would be the plan to run all of the underlying services?

Yahoo is PHP and MySQL headquarters to some extent. Rasmus Lerdorf works at Yahoo! and I can still remember downloading MySQL from Jeremy Zawodony’s server (it was listed in the US MySQL mirrors for a while).

John goes on to ask “When was the last time you saw a new hit web site developed using Microsoft’s web stack?”. Well, Google’s Orkut was built on Microsoft’s .Net platform, but I heard they had some serious issues with scaling it.

Personally, a merger between the two just seems like a disaster.
