There are many reasons to care about one's UA score, but of course that all depends on how wide UA is integrated throughout the Steem Blockchain and multiple services:
- @punqtured from ByteBall for example wants to integrate UA to determine ByteBall airdrop amounts with, and determine if an account should be eligible for a Steem Attestation at all;
- @smartsteem will use minimum UA-scores to use their bid services at all
- @steem-ua (our own algorithmic curation service) goes one step further and computes not only the UA-Author scores but also the UA_Post scores which incorporates all votes on any post by looking at each voter's UA score, not their SP.
... and I could go on with these possible use cases until this comment is longer than our intro post ! ;-)
UA has many, many applications
Vote trails can customized their vote strengths according to UA score..
