It certainly gets more complicated if you follow more than one unless you have a very large account. You will probably find your voting power keeps hitting the lower limit and if you reduce the upvote percentages then you will start to generate "dust".
So whilst it is commendable that you would like to help as many as possible it makes a lot more sense to wait until you have 100s of SP.
OK, thanks for that I may need to make a few changes then, like I said...still trying to get my head around it all, does this apply to the curation trail, or the fanbase, or both? And would just disabling some of them work (rather than unfollowing)?
Both and yes you can disable them so they are ready for when your account grows.
Thanks for the info, that was really useful (no really!), I'll just set it up for Musicvoter for now then, hopefully I'll grow enough to follow the others I was following (just on disabled for now)
