i am thinking of using multi-plant photo id's as hash tags - so that i can discuss the plants in multi-photos later perhaps and find all the posts related the them later, at once.
wouldn't it be useful to get a list of hash-tags for each blog up-front (if it's not too long...)? so you know what the blog 'themes' are, perhaps?
when the blogs mature and get long they could be difficult to navigate.
i wonder what other people found useful as hash tags in blogs, besides month-year or some plant-group name, for example, like bromeliads?
