Basically, we are working on public beta which is due late this month,
so we can get more exposure and users drive more feedback to improve
the site. We need to setup some a better feedback system like
uservoice or getsatisfaction which would do what you say in terms of
voting.
In terms of future features we have various plans of bits we want to
improve and add, however we often drop these plans when it doesn't
work out or priorities change etc. so I'd rather not announce features
until they are ready (which typically go on our twitter
(@friendbinder) or blog -
http://blog.friendbinder.com )
What is always useful, however, is for people to tell us problems with
the site and to tell us the pain points they have dealing with
multiple sites and social networks in general so we can try to find
solutions.
You can put suggestions either on this forum (like you have done) or
if you prefer via email at contact at friendbinder dot com (or
numerous other ways like on your blog, twitter etc.)
