I just came up with your call on updating linguistics Wikipedia and got enthusiastic to take part in it. I'm a linguistics student (MA) of BuAli Sina university of Hamedan, Iran and found that the list of linguists is so incomplete that none of Iranian linguists are included. I can help on the completion of this part.
Moreover, there is another point that I think will play an important role in having a more professional Wikipedia in our field: professors can also be classed as specialization. to be more specific, for example in Pragmatics page, a "Specialists/experts" entry can be added. This way, academics of any kind would have a more practical search experience and access so much information with no need for extra explorers.
I look forward to hearing from you.
