YSK adding tags will make your posts more discoverable on the wider Fediverse
On KBin we have the ability to add tags to posts. These can either be directly added using the “pound” sign octothorpe, as in #KbinMeta. You can also add tags using the “Tags” field when creating an article, link, or photo. The second method will append the tags to the end of the post when the post is federated.
This is invaluable for your post to be seen on other platforms, especially those without any algorithms, such as Mastodon.
KBin magazines can also have tags associated with them. This will associate content from the Fediverse that uses those tags with the magazine. Also, very useful for smaller magazines.
If you want to view content related to a specific tag, you can visit <Kbin instance>/tag/<name of tag>, ie: https://kbin.social/tag/kbin
£ is a symbol for currency (Great British Pound or "pound")
lb is a non SI symbol for weight (pound or 0.454kg)
# is a hash
Systems need ways to recognise tags, prefixing them with a symbol is helpful for computers. Using # as the prefix makes it a hashtag #technicallycorrect
It is believed that the symbol traces its origins to the symbol ℔ an abbreviation of the Roman term libra pondo, which translates as "pound weight"
A 1917 manual distinguishes between two uses of the sign: "number (written before a figure)" and "pounds (written after a figure)". The use of the phrase "pound sign" to refer to this symbol is found from 1932 in U.S. usage. The term hash sign is found in South African writings from the late 1960s and from other non-North-American sources in the 1970s.
