Hindi Wikipedia has one lakh articles. A lakh is 105 and it is one of those numbers we happily recognise as a cause for celebration. So, congratulations to the Hindi community and lets hope that this auspicious occasion will translate in a project that will be increasingly popular.
A lakh is a unit in the Indian numbering system. These numbers are written differently from what most of us are used to. It just happens to be the same as 100.000. Numbering systems are defined in standards and, the appropriate standard is the CLDR.
Given that we do support languages and consequently peculiarities like different numbering systems, there is a Bugzilla bug asking for the support of the Indian numbering system. It has been scheduled for proper attention and, that is a sign of the Wikimedia Foundation doing good for all the cultures it supports with its projects.
