I'm sure all of you have already read my
Apologia for RSS (the very
first post on this blog!) and I'm sure you're all reading this
in an RSS reader you've chosen for one reason or another. But
does your RSS reader show you everything a post
contains, or is it hiding the deepest, juiciest quips and
chatter from you?
I've been on Tumblr since
its heyday back in 2011, and it's now the only social media I
can really say I use regularly. One of the aspects of its culture I appreciate tremendously
is the concept of "chatting in the tags". Tags in Tumblr are
snippets of text attached to both posts and reblogs, but only
the original instance. If you reblog a post, that reblog
doesn't include the tags of whoever you reblogged it from.
Although tags were presumably intended primarily for
cross-referencing posts on the same topic, Tumblr culture has
adopted them as a way of writing
sotto voce commentary on posts, visible only to
people who are following you specifically without escaping
into the larger network. Sometimes people use this to be
funny, sometimes to relay anecdotes, sometimes to be catty.
Universally, it gives a window into the personality of the
person you chose to follow, above and beyond just their
curatorial decisions about what to post.
Even on one's own posts, tag chatter provides a means of
adding a bit of commentary that's tangential to the post
itself, of a different tone, or a little more personal than
they want escaping into the wider network.
One of Tumblr's virtues, and in fact one of the main reasons I
still use it at all, is that it provides RSS feeds for every
user. These are the main way I read the website at all! What's
more, these feeds actually contain that user's tags. For the
technically-minded among you, the feed entry looks like this:

Those <category> elements are the tags.
Neat! But totally useless in practice unless a reader actually
displays them.
