No - it's because you've done something you think your friends would be interested in and it's a lot easier to take a photo and click 'post to Facebook' than to write to 30 people.
That's really the fundamental function of Facebook and any successor will probably succeed by doing it better in some way. eg. Snapchat enabling you to send naughty pics without them being archived on the web for the rest of your life and so on.
Then, Facebook filters all my friends' feed so only 50% of them see it.
All I want from Facebook is a way to reliably see all the posts from all the people I want to follow, and have it keep doing that. I have found settings in the past that let it happen, but it seems to reset to filtered every time I take my eyes off it.
Is there an easy way to choose who sees a particular post (ie, the way one sees a display of friends to click on when inviting them to an event)? They should implement this, allowing for deselecting unwanted viewers (rather than selecting for wanted viewers - for those with too many friends).

Just to offer a different perspective: to me, the valuable part of sharing life events is the engagement with another person. IE, the extreme convenience (broadcasting 1-to-30 people) undercuts the reason for sharing: connection.
(I also have recently identified concerns I have with group mechanics, and this no doubt influences my perspective.)
I'm posting a picture a day. Surprising how many people go out of their way to mention how much they follow & like it.
