For existing long-time users this seems like a backwards step, and indeed I fed this back as part of this request for feedback on the new design;
From this, it looks like they’ve got a plan to revamp the forum area and there must be something driving it. It’s not called out specifically, but I would imagine this is aimed at users who are new to Webflow as we all know the focus is growth and onboarding new accounts (I can’t seem to go anywhere on the web without seeing a Webflow ad right now…) and anything they can do to engage those users is likely to aid revenue. I imagine it’s a product with a high fall-out as it’s certainly got a steep learning curve for the inexperienced users that are targeted.
Give them the feedback. I’m sure they will likely have a target to achieve with all this which will be measurable in some way anyway ;)
