Is there a reason for the "need" to move tumblr over to wordpress?

As noted tumblr isn't profitable, why expend all that effort and cycles if being on a different back end doesn't change the nature of the product's profitability?

Sounds on the surface like a very engineer type decision where "it would be better on this technical X" doesn't really change the business at all...

So lemme get this straight. He put off the migration to a different back-end because they couldn't afford it. So then he moved or fired people to get the costs down... but still wants to do the migration, now with even less people to get the job done?

Make a decision, dude. Either invest in the platform or not. Don't shrink the staff while increasing expectations of what they must deliver.

I think we could come up with some much, much bigger failures.
