Great insight by Basecamp founder Jason Fried on how Instagram and Twitter feel different:

Every scroll through Instagram puts someone’s good day in front of me. A vacation picture, something new they got that they love, pictures of nature, pictures of people they love, places they’ve been, and stuff they want to cheer about. It’s just flat out harder to be negative when sharing a picture. This isn’t a small thing – it’s a very big deal. I feel good when I browse Instagram. That’s the feel that matters.

So now I have a choice… When I have a few minutes to kill, and my phone is in front of me, I almost always reach for Instagram. I never regret it. I come away feeling the same or better. When I occasionally reach for Twitter, I discover someone’s pissed about something. I often come away feeling worse, feeling anxious, or just generally not feeling great about the world. Twitter actually gives me a negative impression of my friends. I know it’s not Twitter doing it, but it’s happening on Twitter. that’s how Twitter feels to me.

I’m on Twitter every day and it’s definitely a place to show off how witty, topical or pissed off you are.

Instagram is just where i like to post pictures of cars I find.
