I would fit into the 'potential employers' part of your comment, having hired <50 people in the last 12-18 months (and 100's total in my time). If I got a candidates name, and Google'd them (which I always do) and a blog post like this came up: it would have no negative effects on my view of that candidate.
In fact, I would prefer a candidate who knows their limits and is obviously willing to communicate them. I would view a person who would publicly talk about a subject that few others in their position do as someone I would want on my team, as I would view them as more likely to not only push when their workload/lifestyle is becoming unhealthy but would actively help in recognising it in others who maybe wouldn't talk it so readily.
Frankly any organisation that would view something like this as negative is one I would council no one to want to work with.
