Totally agree, and I think there is a general consensus system-wide that the delivery of such capability is now part-and-parcel with Steemit's growth aspirations.

I often have content that I don't want to direct to ANY one language in particular. Whoever sees it, and wants to engage, however they want/can, is sometimes my goal.

Exactly how to best achieve that is the million-steem-dollar question, however. If adding language tags is too laborious or convoluted a task right now, I'd settle for a solely visual queue in the interface itself, for awhile (e.g. language icons).

For the interim, I might just add some brief language details to the footer .gif I was looking to have made to trail each of my comments. Not searchable at all, but still something...
