This is my opinion/vision. Not representative of HQ/Shawn's future plans with the area.
It seems like some people think we've done away with Welcome Lounge. The core of Main Street remains the Welcome Lounge. There's no difference there. It's a place for members to head in, feel welcomed, and start their interactions with the broader community. On top of that, we are going to be looking at member events, member spotlights (something we've not ironed out yet - it's something I'd personally like to help Shawn with as well!), AMAs, and as much member "interactivity" as possible.
Spotlights could be member-chosen, so the entire member base can nominate people to get to know more, whether they're new or old - akin to El Heroe's old Member Blogs. This encourages discussion, interaction, questions, and getting to know a member in a short feature similar to the ME threads, but also eliminates the eventual "dying out" of the threads in ME. New threads got traction for a short period and then died. There's barely a handful of threads that lasted longer than a month or two and after that, the members themselves had to bump them. Not really a thrilling area and the tools to get to know and communicate with your fellow members are available in many other places.
AMAs would take a different approach and could still be member-chosen if that's what we feel is best, but we'd be looking to spotlight members with unique perspectives and careers and lives. We have members that work for Apple, Disney, Sega, the movie industry, the scientific community, developers of websites, and many more unique fields of interest and that'd be a great thing to feature that are separate from Spotlights.
We've taken the good elements and good potential from ME and we're trying to re-tool them into this new area. ME was really not that fun or inviting for a majority of the members and once the thrill of a few questions died off, 98% of the threads died off as well. We don't usually give members notice of changes we're making until we've made them, but I can assure you this was discussed well and there are optimistic outlines and goals ahead.
All of that to say that I personally want to feel and see more members heading into Main Street to take part in welcoming our new members, getting involved with celebrations, and interacting with new features we'll be looking to add. Those are just some base thoughts on the topic. Once again, I'm speaking myself here and not laying out any goals for the area exactly - just my idea of what is possible with a fresh look and a fresh area - especially given ME is 1) mostly a ghost town 2) unavailable to a large number of members.
