The part that has impressed me about Twitter/Vine/etc over the past few years is their content embeds in other sites/services. Their main apps are so riddled with junk that I hardly use them. The real estate in their feeds devotes more to ad space than micro-blogging, and everyone knows that followers (/follow-for-followers) are a marketing cesspool.

Twitter et al. should really become the blockquote service for the internet.
