For me there are two concerns: First, with anything “like this” I don’t necessarily worry about any of you people being able to figure out who I am in meatspace. But I’d rather avoid creating direct linkages. Especially in this context when I’m sharing deep, “dark” secrets.
The second is that to identify myself in the databases of the world would also effectively identify my SO and potentially any current or future lovers. I’m self-employed (and work in software anyway), but she’s got letters after her name. So we maintain an air gap.
