Not updated, important services do not work properly... Rated 2 out of 5 stars

Apparently has not been updated for a while :(

Does not work with (and yes, I had the correct API key and user name) - all I saw was sidebar with something like "Unable to shorten link:..."

Has troubles with character encoding in gmail - I am from the Czech Republic and it corrupts diacritics in Czech web pages - try e.g. 2001:

In message subject I get: "Vesm�rn�odysea / 2001: A Space Odyssey (1968) | Č"

Did not tried other services, could be a great addon though...
