Well... there are a few, which I read/watch everyday:

• Elon's twitter account: https://twitter.com/elonmusk/with_replies
• YouTube and many "Tesla YouTubers"
• tesla subreddits: https://reddit.com/r/teslamotors/, https://www.reddit.com/r/teslainvestorsclub/

If you will search on new videos about Tesla on Youtube, by searching Tesla and enabling filter "Today", you will always get a lot of good materials :)
