I have got the Entrecard widget remove from Sherry Contest's blog. I cannot login my account at the moment in Entrecard, below is the reason.
Entrecard application server failed
The server that does the complicated work has not responded in time, this could be due to load, due to an upgrade happening, or something else even weirder. An alert should have been triggered to the admins so they're no doubt trying to deal with it right now, we recommend trying again in 10 minutes.
