I seldom read resteemed posts either. Unless it is a topic that I am interested in or an author I really like. Services that offer you resteeming services and just fill their feed with hundreds of randomly resteemed posts are totally worthless in MHO. I do use ginabot and steemworld.org for monitoring my mentions and comments. I try to keep up with them so that I can reply to people kind enough to make comments. I also do not mind getting memos to my wallet. Like you mentioned, if it's something that's not relevant to me, I can just ignore it, no harm done, no need to be upset about it!
