Read more / post expansion button as opposed to new page

First of, thank you for the mobile friendly text editor (I see it hasn't been extended to writing posts yet but that is understandable as one of the great things about this site is the ability to mark up your texts properly). It makes it a lot easier to get involved, at least in the comments where you generally don't need this amount of control/mark up.

Now onto the actual idea here. Currently this site has seen two systems for dealing with posts and the main feed: seeing the full post and (the system that is used now) seeing a portion of the post until you click on it and get taken to another page. This latter system works great in the sense that it consumes less data if you're not interested in a lot of posts in your feed. However loading up the new page takes a bit more time, and you can't see the other discussions at the same time unless you go back to your feed.

So another possible system, although I'm not sure how one could implement it, is to expand the post on the page, the feed, itself. As for UI, you could use downturned chevrons for example (I found most people think it's more aesthetically pleasing than "read more..."). Comments still wouldn't be expanded until you click on the comment icon, so you could still easily scroll across your feed once expanded. The chevrons would turn upside once expanded so it can be collapsed again (a slight "turning" animation could help aesthetically).

Now if you could dynamically load the data, this could cut back significantly on the resources loaded. You already have the majority of the page loaded, the only extra info you'd load is the text in the post. I'm not sure how efficient loading different pages in their entirety is though, I don't know much about dynamic caching if that is even a thing.

Thanks for taking the time to read this. Loading posts on different pages is only a minor annoyance, so it shouldn't have priority, but I do hope a better system could be implemented sometime in the future. Keep at it guys, 'cause you're doing great.
