This is my first post on Cake. I'm one of the remaining Google+ users looking for a new home on the web - and while I think that I will use my own webspace more often from now on, so far this platform seems to be the most attractive among the alternatives that are being discussed at the moment. I have a huge variety of interests, some of which come and go over time, so this idea of being able to freely post to random topics and have my post seen by people interested in it, without any need to first make connections by "following" them or trying to be followed back, is intriguing.
One of my interests is photography. On Google+, one way to get the attention of others interested in the same type of photography was to post using the hashtag of a "photo theme". An image in black&white could have been posted with the #MonochromeMonday hashtag, or an image like the one I'm attaching here(*) could use a hashtag like #28DaysOfFall. I wonder what others think: is it a good idea to use hashtags here as well, to make posts searchable even across topics?
For what it's worth, would it perhaps even be a good idea to automatically turn (up to) the first five hashtags used in a post into topics?
(*)I found this leaf in an empty parking lot while on a walk last weekend. In my images, I like contrasts of all kinds - and this colorful, weirdly shaped leaf on a nearly monochrome background with its regular pattern is something I just needed to take a photo of.
