It's hard for steemit not to have some sort of exponential growth. Never has there been such a platform so decentralized and with such noble aim of providing valuable incentives and rewarding users for their opinions with no form of bias whatsoever.
Utopian.io is the next best thing for open source(thank you @elear), I used the platform recently to post a documentation I'd written for UNDERSTEEMED a very nice tool developed by @tabris. If you are a developer or anyone for that matter and you think you have wonderful contributions to offer the steemit open source community do check out utopian.io
It's very encouraging that people see lots of possible believe in this platform enough that they want to keep contributing to its growth so it doesn't become obsolete, I think that's the beauty and driving force behind the upward spike of this platform.
Thank you @exyle for sharing this, you are the best
