Last month there were around 386 official solution partners listed on magento.com. Today, only 281 are left.
What happened? Well, Magento kicked them out (gently :)).
Last year at the Innovate conference the Magento Developer certification was introduced to give developers a chance to prove their Magento skills. This also gave Magento partner companies a way to differentiate themselves from other companies with the number of certified developers working for them.
