Greetings Viking God,

I'm afraid that you are correct, and we indeed don't have any
up-to-date obfsproxy bridge bundles.

The main reason for this is that we lack manpower and making proper
bundles takes a while. It took lots of time and effort to build
PT-supporting TBBs (check out tbb-3.6!). Making bridge bundles is no
easier and probably requires extra UI work so that users can configure
their PTs.

Also, because we have many tech-savy people running bridges in
powerful Unix systems, it's easy for us to claim that spending all
that time just to support a few Windows boxes under home Internet
connections might not be worth the time and effort.

Also also, we are moving away from Vidalia (see the latest TBB
releases), and I'm not sure how future bridge bundles are going to
work. That is, whether they will use Vidalia or tor-launcher will do
that too.

That said, you are absolutely right that this is not optimal and by
doing so we are ruling out many potential bridge operators. We should
get back on track with this project.

BTW, if you want to help with this, you might want to join the PT
meeting we are doing tomorrow at 17:00 UTC in #tor-dev. And there is
also a TBB meeting at 18:00 UTC, so it's a very good opportunity to
get up to speed with what needs to be done.

I don't have a definite explanation on why your traffic diminished
like that.

As a possible scenario, BridgeDB has been experiencing some technical
difficulties lately (for example, the CAPTCHA is stupidly hard to
solve), so the number of people getting bridges of BridgeDB might not
be that great. Most clients are probably concentrated on the bridges
that are included in the bundles, and the bridges that are passed
through the support team.

I still don't know how much traffic BridgeDB bridges yet, and whether
you are going to get more clients if you run a bridge now. Hopefully
you will. If not, you might want to send your bridge credentials to
the support team, so that they can personally pass your bridge to
users.
