Things have been pretty quiet and steady for the last few weeks. This is mostly deliberate on my end—I'm going to be away for about a week around the end of the month, so I didn't want to make any major changes or push for a big burst of new users when I might not be very available to deal with any issues. Most of my time lately has been working on stuff in the background, including doing some cleanup, finally getting around to various things I've been putting off for a while, and so on.
However, in early December I'm planning to move forward into the next "phase" for Tildes, which will be making it publicly-visible so that people are able to visit and read the content here even if they don't have an account. Registration will remain invite-only, but I'll probably try to make the process a little easier or automated in some way so that it doesn't require so much effort from people like me and @cfabbro (who's been diligently running invite-request threads on reddit for months).
Overall, I think that being publicly visible should help a lot, both to increase interest for the site as well as addressing a few common misconceptions about it (which are mostly because people can't see anything for themselves). Right now we're effectively "wasting" a lot of invites by forcing people to get an invite and register before they can even see if Tildes has anything they're interested in, so opening it up for everyone to be able to view should make invites a lot more efficient when they're only requested by people that want to participate.
One thing I should mention is that I'm not intending to have a "default front page" for logged-out users. They'll need to choose specific groups to view, and I've been playing around with a few ways to try to make this convenient (that will probably end up being available to logged-in users as well).
It's also been a while since I gave everyone more invite codes, so I've given everyone 10 now. If there's anyone else you want to invite before we get into the publicly-visible stage of things, you can get your codes through the Invite page (linked in your user page's sidebar).
Please let me know if any of you have any thoughts, questions or concerns about becoming publicly-visible, so I can see if there's anything else I'll need to make sure to address before being able to open it up. For example, are there any features that might have a privacy concern when public? Should we consider making any changes to the current set of groups? General feedback and questions unrelated to the public visibility are fine too (and always are—you can always feel free to message me or post in ~tildes).
