I'm not sure, that's why I'm asking what they are called... But the objects I am referring to are the hashtags at the top of the front page in a horizontal arrangement. They seem to be hashtags like regular tags, but are listed as feeds, then I heard somebody call them community channels, etc... I'm just lost when it comes to how many "things" there actually are. In other words, are all of these items just tags or is there a difference between a "node" and a "channel" and a "feed", etc... They seem like they may be the same thing in the back-end and the front-end renders them differently but I'm not sure... But regardless of implementation details, I just mean at a semantic level, what is the structure intended to be?
