1. Mahalo is blowing in the wind. I have no idea what Mahalo is or what Calacanis wants it to be. SEOing the hell out of near-worthless content is not a long-term strategy. If you want to win - solve a problem!
2. Jason Calacanis is an excellent executive. This Google algo change took place on Fri/Sat. By Tuesday this guy made the huge, painful, most difficult call in the world and laid off 10% of his company. If you have ever had to lay people off - you know what I mean. It is hard, it is painful, it is life changing. I wouldn't wish it on my worst enemy. I understand that the employee takes the blunt of the blow - but believe me, being on the other side of the table is not a desirable place to be.
I know this is not a popular stance on HN, but I have a lot of respect for Calacanis. The guy has done so much for the start up community. TWiST is some of the most valuable content I have found on the web and The Launch Conference - if it hasn't already - will change the startup conference scene forever. Not to mention his home brewed angel network that tilts the table in favor of entrepreneurs.
Calacanis is a hell of a self-promoter - but even if he rubs you the wrong way - you should respect what he has been able to do. If you have been (or were) on 60 minutes talking about internet startups...in your 20's...feel free to rip him apart. If not, show a little respect for what he has done and little empathy for what the guy just had to do.
