firstly, the climate permits it. i assume now that any company holds a latent 10% rif in good times, just waiting for a bad market so it can lose the 10% to throw the market a bone
secondly, consumer/business software and the web are exiting the innovation phase and entering the cost phase. yeah this will get all the yc types in a tizzy, but its true. the consumer web has been "built" as far as 99% of users are concerned, and most of the major platforms have evolved to the stage where large headcounts are not needed. business software hasn't changed substantially in years. the winners have been picked and now that margins are shrinking, the way to a better top line is most easily achieved by moving the bottom line.
oh well the fun had to end at some point. between moore's law making any idiot a passable coder, oodles of great free and open code, and winner-take-all economics, my opinion is that coding won't be a desirable job within a decade...even in startup land it is about the gimmick more than the code these days
