This is yet another social bookmarking viewlet based on
http://www.addthis.com/
Why a new one and not for example collective.addthis? Well,
probably just because it is so easy to generate the javascript with
the services we choose, and register this as a viewlet. We did that
for our own Zest Software site and a client wanted the same, but
then with a checkbox per page to turn it on or off.
This gives you a viewlet near the bottom of the page with links to share this on LinkedIn, Twitter or Google; you can share on some other sites in a popup; plus a print button.
Also, you get an extra boolean field show_social_viewlet on the
edit page (the Settings tab) of content types (using
archetypes.schemaextender). When this field is checked, the viewlet
is shown. By default the field is not checked, so the viewlet is
not shown.
The extra field and the viewlet are only available when you have actually installed this Add-On in your Plone Site (this is done using plone.browserlayer). So when your Zope instance has more than one Plone Site, the viewlet is only used in the site where you install it.
There is no configuration in the UI. If you want to override the
default value and fallback value for showing the viewlet you may want
to look at config.py and do a monkey patch on the values there.
If you want to change the links that are shown, you should just
override the viewlet template, which is probably easiest using
z3c.jbot_.
zest.social has been tested with Plone 3.3. and Plone 4.0, using
archetypes.schemaextender_ 1.6 and 2.0.3.
