@phocks painful as it might sound, unless I notice the typo straight away or the error really is very misleading, I leave it as it is
Fixing a typo on a post after people have liked or boosted it sends them all a notification. This is an annoyance, but a necessary one because the meaning may have changed
Personally if anything I've boosted gets edited more than 30 minutes after it was posted I just unboost it. I kinda wish that could be automated instead of me getting a notification
