I run the Python meetup in Thessaloniki, Greece, and it's exhausting trying to find speakers.I frequently skip months because nobody wants to present anything, and we aim to have two presentations on each meetup. I'm almost always the second presenter, and sometimes I'll do both presentations myself (or just skip that month's event).

It is exhausting, and people do always ask when the next one is, but my reply of "whenever you want to speak" doesn't seem to do much to get more speakers.
