This works well if you're: - In the same or a similar timezone as the person you're talking to - The one initiating the conversation (this is often not an option if someone else emails you!) - Don't need to keep a record of the conversation - In a situation where a meeting or phone call makes sense Note that many of these are often not the case in e.g. the FOSS community. I'm therefore not surprised that those on FOSS mailing lists avoid top posting.
