Interesting. I have to admit, I've always found reblogging annoying. Firstly, because it shows up on my own blog on PeakD when I reblog and secondly, because I usually wasn't interested in the reblogs of the accounts I follow.
But I agree, it really is a good feature to get some exposure as a smaller account. I think I will reblog one or two blogs in the future, but only if they are of high quality of course.
Thanks for your insights on this!
I would also advise new users to make use of both reblogs and comments, as these are the interactions most likely to appear in others' notifications. This approach works well for those who are just beginning to build their HP.
However, you make a good point—reblogging can overwhelm someone's feed, especially if done excessively.
