From another designers perspective,
In terms of the logo itself it's fine, but it could have been better executed. I would have liked to see a logo that flowed more cohesively and perhaps even an updated version of the icon (retaining the concept, but reinventing it in a modern way.) As for the word mark, there isn't really anything special about it and while it is a lot cleaner and more legible I don't know if it truly screams "Second Life" to me. I do personally prefer the change from green to blue, yet the reasoning seemed a bit forced. Overall the logo isn't anything special, and that is fine.
In terms of the announcement and overall rollout thus far, I feel as though it could have been done through a proper press release followed by a unified update to the websites and social media platforms... I do understand that they have different teams managing different aspects of the brand but I believe it could have been introduced in a more formal way rather then just saying "hey guys heres our new logo!" it just seemed a bit unprofessional in the grand scheme of things.
At the end of the day, it was time for a rehash on the brand and I'm looking forward to seeing how they implement it across the platform.
