I probably do not have a popular opinion about the trails. I'm not saying they are bad. In fact they absolutely serve a purpose for their communities - but they are pretty specific communities. If you do follow a trail be sure to track your vote power as some of the trails are aggressive curators; which is their purpose - to find posts which have the potential to earn, which can help boost a percentage of your earnings. I'll be honest though, it's been a good long while since I've joined a trail and I'm really out of the loop. Sorry I couldn't be more helpful on that.
