One thing that has always bothered me about Pinterest is that you can search by keywords but you can’t follow keywords. If I’m interested in movie memorabilia – I can follower pinners who often pin movie memorabilia, or I can follow boards pinners set up that are all about movie memorabilia but I can’t follow all pins related to movie memorabilia.
In the near future, that could change.
Pinterest just started rolling out Pinterest Interest filters, some of which come with their very own follow button.
It begins with high-level topics such as Hiking or Camping. You can choose to follow at this level or drill down to a more specific level such as Hiking –> Pacific Crest Trail.
