It was nice to recieve a message like that one, from the foundation. We at Hindi wiki are constantly making hard efforts to upbring the Hindi wikipedia. During that if someone praises our effort or asks like this, is like a glass of cold water when you are working in a desert. Well now coming to your queries:
By Indian wiki community I am replying for Hindi one only. We are not so strong at electronic media to convince anybody for contribution here. Well then we have the only way by mouth (Also telephones) to aur friends & contacts to start contributing at Hindi wiki.
We here have been working hard to uplift the Hindi wikipedia. A few deeds to give a refreshing look to the front page are:
We have been updating the Featured article bimonthly, & also planning to change it monthly, but due to sudden lack of active Sr. workers, just continuing the bi-monthly status. We can still now change it monthly, but due to strict quality considerations, maintained the status.
We update the featured picture on weekly basis, in which many a pics are coming in between, on special occasions.
We are daily changing a new article for Aaj ka aalekh (Today's article), which is of short length (250-400 or more words)
Last year, we started a drive in the month of August, nearing to Hindi Day, to achieve a target og 50,000 articles. And also achieved it.
Regarding Hindi wikipedia, if any staff at all is to be put up, any metro can be chosen, but as considering Hindi, so Southern India may be ruled out. Similarly, west & east can also be on a lesser preference to North India. Well that way as per Hindi speaking metros, Delhi, Lucknow, Jaipur, Chandigarh, Allahabad, Varanasi, Patna, Bhopal, Agra & Gwalior can be considered. Now here Patna has its own Bhojpuri wikipedia, to which it is closer than Hindi. Similarly Chandigarh is closer to Punjabi one. Now on the basis of IT facilities except Delhi, all other cities are behind Delhi here. Delhi also enjoys the status of Capital. Well that way Delhi has the max points in favour. Pls forget that I am fm Delhi & so canvassing for that. Still many of the Hindi wiki users & Sys-admins are from here.
Last but not the least, the foundation can help by setting some Internet cafe like parlours, where interested people can come & contribute. They can have information, guidance, facilities, concessions, etc.
Rest what our tireless contribute Gunjan has said above is also useful.
