In my opinion, "time" is the biggest one; he mentions it first, but I don't think the gravity is expressed adequately. I have time to waste on HN because I spent a year and a half building the one I'm on now; at this point a blog... just doesn't matter. That's most certainly not meant to be a general comment, but in my case, time was a problem to the point where, once it wasn't (as much), a blog was no longer valuable. Whether it's valuable or not is highly dependent on your product, your goals, and your audience. I don't think there are many areas where it's totally worthless, but if you're actually an entrepreneur and not just tentatively trying something out and looking for backers, in my experience it's hard to find enough time to both blog and promote your blog unless you're either a minority-share-of-the-grunt-work partner or already so plugged in to some popular scene that you don't actually have to worry about the exposure a blog would otherwise be intended to bring. I guess the point of this is that "I can't blog" is the equivalent of a first-world problem in a first-world profession: If you have the time and/or connections to do it and make it effective, it's likely you'd succeed in a very similar way without it.
