I wonder if the OP has ever even seen Pentagram's earlier work. This assumption that all branding has been slaved over, or that no one has ever come up with a good brand in a short period time, show a lack of understanding about branding AND logo design. Sometimes the quick ideas are the best ones.

You got all that from my post which said nothing about a logo needing to be "slaved over"? It does, however, take some thought.

Perhaps you were referring to my comment about Mayer, whose creative output amounted to a collective shrug, as she (and, sure, the design team she micromanaged) produced a logo that did nothing to communicate a new strategy, vision, or purpose.

Which is perhaps appropriate for Yahoo, after all.

Perhaps being so dismissive about something that is potentially very useful for seeding new ideas about identity wasn't the ideal way to present yourself. Unless that's your personal brand voice, I guess?
