I'd rather not put any icons your site that (such that they are
visible by default) that are associated with for-profit
corporations (such as facebook.)
However, I do like the idea of having a single, generic "share"
button at the bottom that pops up a list of sites you can
share/post to. And Facebook and Twitter should probably be in that
list (probably with icons.)
I'd like us to host the source code for it, and be
able to change it, etc. Starting from some open source solution
like http://www.enthropia.com/labs/share/ might be handy. Or it
might be easy to do with just jquery.
I want it local and editable because:
1) Should load fast, and it should not change the height of the
page when it finishes loading.
2) Then we can tweak it.
3) The sites offering an api to do this seem sketchy, I don't want
to rely on them, or give them our website statistics. And I
certainly don't want them to get to choose what sites we can link
to.
4) I'd like add identi.ca, prominently and be able to add a link
for a free software federated social networking service if/when
one becomes available. Both to support these services, and
because our target audience is often the early adopters of these.
It also nicely reflects our values.
That's my $0.02. I might have time to fiddle with implementing this
in a week or two. (If people like the idea, and nobody beats me to
it.)
Take care, - Jason
