Thanks! Good question, I forgot to add that to the help section :) B = board t = topic b = bookmark bt = bookmarks per topic The percentage is the "coverage" received by a given topic in each board. If a board has 10 bookmarks and 3 of them are labeled e.g. "topicX", topicX's coverage is 30%. Totals may add up to more than 100% due to multiple topic assignments. It helps you figure out where you stand in terms of the information you collect. I sometimes have to e.g. research and compare a number of topics within a given theme (e.g. companies in nanotechnology), and I want to make sure I do enough digging on each one. I'm here if you have more questions!
