No more +1 in the Play Store. Consequences?

Ok. It seems that there is no more +1 button in the GP store. No more Google+ integration in Google Play Store | What are your ideas then for how to get into “similar apps” or “others have also installed” categories? Any impact on your downloads?

‘Other have also installed’ where never driven by +1, I honestly doubt it was ever factored into ‘Similar apps’ (I might be wrong here), but since you mention it I’ve just realized that it probably was one of the positioning signals since there was a lot of changes in search position that coincide with +1 removal (see here: I’ve initially assumed that this was due to new categories introduction but this seems to be more likely cause.
