Colin Devroe made a good point.
He is subscribed to my main feed and wondered why he didn't see my Watch follow-up post about the woman on the train.
The answer was that it was a microblog post and, therefore, in the /feed/microblog feed instead.
Emailing back and forth about it made realise that this is a bit pointless.
I was originally going to keep the microblog separate from the longer posts and, because micro.blog doesn't want post titles for micro posts, set up a custom feed with no item title element.
It was my intention to not include the shorter posts in the main feed as it had always been for more essay-type posts but, ever since I decided not to separate micro posts on the site, I have been using standard and status posts interchangeably - the only difference is whether they have a title or not.
So, for common sense to prevail (and for related posts not to be ignored based on length) I am going to remove the exclusion for micro posts from the main feed.
The microblog feed will still exist, as will the separate podcast feed, but everything will now be in the main feed.
It has been quite a moot point anyway. A status post of 281 characters without a title would have already been included in the feed being not be added to the microblog category.
Arguing the toss over character count is stupid.
