I do, I hate when I do it. It also doesn't add to the conversation. Especially when I do so on items that are questionable, as this one is. What bothers me most is that the level of snark I use is dependant not on the level of offence, rather the number of times I've encountered this varian of low quality comment during the day. This example, although I stand by it, clearly is not one of the greater offences, and yet has maximum snark. The greater problem is these conversations actually often surpass the quality conversations being had in the thread.
