Don't worry, Invision Community is in very capable hands. While I co-founded the company 20 years ago, we've come a long way since then. Along the way, we've hired some extremely smart developers who do the bulk of coding now. I still work on features and help direct the product, but I spend less time in a code editor these days, and that's a great thing.
I enjoy writing, and if one person gets a little value or inspiration from a blog article, then it's been worthwhile.
Really soon. A soft release helps us narrow down critical issues before we roll it out to all customers.
