Adding to this reddit is centralizing themselves. Classically they were a link aggregator, a place pointing to other content. Now if you upload something there reddit is the place its pointing to. A video on reddit is hard to download, and a link to a video is always opened with a full reddit view with comments and everything.

I dont like the way they are going and have sought alternatives 2 years ago. Thats where i found hackernews and tildes.net which are pretty good. However not a good alternative to the niche subreddits we all love.
