here’s the great thing about writing - it changes with you; for some of us, that means daily; for others, that means quarterly or yearly; writing moves with you - and your brain. As your brain realizes new aha! moments, insights, words, etc., so should your writing.
pair that movement with the magic of websites, and that means you can shift, change, tweak, edit website copy and stories fluidly. so, unless you’re planning to etch your company’s mission statement on one of ten stone tablets, you can and should tweak your writing - and, in this case, your website copy.
