If we were really going to modify code, the ideal system would be to enter your location on your profile if you want to attend meetups, and allow emails to be sent to people nearby when a meetup is posted in the area. This has the added benefit of letting LW readers who do not go on the site every week find out about them. Although, I just skip over meetups which are irrelevant. a large amount of coding would be required for a miniscule improvement in the site.
