For posts like growth_drive and weight_gain_drive, sometimes goals are set based on 'interaction' rather than donations (donation_drive)

interaction_drive would be for drives in which the next part of the sequence is reached by a certain number of likes, retweets, upvotes, shares, etc.

Also, perhaps we can have tags for the different types of milestones show in the post, akin to donation_goal.
i.e. like_goal, vote_goal, share_goal, retweet_goal (aliasing retweet_campaign)

I just don't want to make the tag before seeing if anyone had any alternative ideas for names and such.

bump :)

Should probably just alias everything to a single tag like milestone_goal, with the associated symbols be tagged separately (such as the likes being heart_symbol and shares being retweet).
If there is indeed a need for subtags, then they can imply it instead.

I'm probably going to start tagging these and create a BUR for the goal -> symbol implications.

If it's decided to go with a more uniform tag like Wolfgang suggested, at least interaction_drive and *_goal posts would be tagged and ready for aliasing, as a lot of them aren't.
