The posting feature/options should be more visible
I think that the posting feature should also appear in the sidebar of a community below the subscribe/block buttons (or maybe below the community description), and the mods could choose which posting options are listed in the sidebar
And "Article" should maybe be renamed to Text Post
If relevant you can use an RSS reader* to subscribe to specific communities, for example https://kbin.social/rss?magazine=kbinMeta (there's an RSS button in the bottom right of every page, next to the theme/lightbulb icon)
I've also suggested RSS feeds for DMs/reports/etc., hopefully this will be added some time
*I use Feedbro on Firefox
Found that it was already suggested :) (and I gave it a like)
I use Feedbro for Firefox (also available for Chrome). It allows you to filter out items based on their content (supports regex), highlight keywords when viewing items, get desktop notifications for new items in specific feeds, and more.
