Isn't 22 minutes the maximum? I mean if 1AU=150e6 km, and Mars-Sun is 230e6 km, and assuming circular orbits, we get a distance between mars and earth of between 230e6km - 150e6km = 80e6km and 230e6km + 150e6km = 380e6km Giving a range of 4.4-19.4 minutes. (EDIT: I guess 22 min is the back-and-forth time) Anyway, this will surely suck, but I often chat with people while they're doing stuff, and they often only get back to me every 10 minutes or so. You just need to multi-task while doing conversation. Also, some reddits only allow you to post once every 5 minutes or so; that's not that different from having a 5 minute delay (note how old posts are that you're responding to). For many people, most communication is already delayed.
