Reddit's growth has been amazing. It gets a lot of hate because of users reposting content without giving credit, but it really is an amazing site. I used to search Google endlessly for sites to get, for example, help on video games or services for video games, but now I think, "Well, I'll just check out their subreddit and see if anyone else has this problem." It's great for news and breaking stories. Sometimes I see it on reddit before I even see it breaking on Twitter.
I think Conde Nast did a good job as well in not fucking it up for the site. They let the owners do their own thing and let the site grow (an action I really wish other large companies would take when acquiring startups) instead of forcing them to put annoying ads all over or other stupid things.
However, I wish reddit would make it easier for users to find features and generally understand the site. I'm still finding useful features that have been hidden in the software.
I thank the reddit staff for their amazing work and hope that they keep it up. :)
