Blogging about sensitive topics

Since I don't think anyone reads my blog (except perhaps my co-collaborator), what would the harm be in posting something sensitive about work, perhaps about business dealings?

I suppose the site could find its way into a Google spider, and then someone googling for their name might be surprised to hear me bellyache about business topics.

So, at least for the time being, you'll have to hear my bellyache in person.
