The good news is that the feed freaking out will be fixed with the next release. If you haven't already, go into your settings and you can block NSFW content from there and none of that should show up. My suggestion would be to go to "Communities" and browse through there to find what you are interested in. I'm no expert and it has definitely taken some time to get used to but I'm really starting to like it here. The communities will grow. If you're not comfortable now, try again in a couple of weeks and see what new content has been added.
