I've been an almost 5 year user of Reddit with roughly 350k total karma. I guess I'm not hip, but I've never taken Twitter with its 140 character limit seriously. That said, I deleted my Facebook a few years ago, and I don't Instagram/Snapchat/etc, so maybe I'm an outlier. Even Reddit is starting to be a bit annoying in that it's an echo chamber, so I'm mostly just subscribed to very specific technical subreddits these days. Finding fresh ideas instead of tired dank memes is often challenging in all but the smallest of subs.
I see Twitter as a platform that exacerbates the clickbait/tabloid culture of shallow bite sized communication. But really, every social media space suffers from the same issue. It's a popularity contest, and what's popular isn't my idea of valuable.
Here's hoping that Steemit manages to support a higher quality of community. From what I've seen so far, there's a strong preference for original content, particularly that which is insightful or well thought out. I look forward to contributing positively. See you around!
