Daily Lemmy comments up from ~7m to ~11m following the launch of Sync?

Unless anyone knows another reason for this impressive increase in comments? Seems to roughly coincide with Sync launching. If thats the case, just goes to show the importance of good third party apps.

EDIT: Looks like a confusingly labeled graph and I think this is total comments. I have no idea why that spike could exist though.
