After much thought, I have had a change-of-heart regarding separate Wikipedias for Low Saxon.
HOWEVER, I still believe it is wrong to divide on national borders. From what I can tell, Stellingwarfs, Grunnegers, Dreents, Tweants, and Achterhooks are all different enough from one another to warrant separate Wikipedias.
Sample:
Stellingwarfs: Et doempien hadde zien nust in et waegenhokke. Op een keer weren beide oolden uutvleugen. Ze hadden eten haelen wild veur de jongen en hadden de jonkies hielendal allienig laoten. Grunnegers: t Was ain van de schierste zummers sinds joaren. n Steltje keudeldoemkes haren heur nust baauwd in de woagenschure stoef achter de baanderdeure. Op n dag sluigen baaide ollen de vleugels uut. Ze wollen veur de jongen wat te bikseln hoalen en luiten doarom de lutjen hailendaal allind achter. Drèents: 't Tuunkroepertien had zien nust ebouwd in 't achterhuus. Op 'n keer waren allebeide de oldeluui uut-evleugen um wat èten veur de jonchies te halen – en ze hadden heur hummelties glad allennig thuus elaoten. Tweants: Et duymke has sin noes in de skueppe. De olden warren der maol ut evloegen, sey wollen wat te aetten krygen vuyr hoer jongen, en hadden de kleinen alene achter elaoten. Achterhooks: Et nettelkönninksken had zien nust in de wagenloze. No bunt de olders op ne kere allebeide oet evloggene ewest, ze wolden wat te aeten veur aere jongen halen, en hebbet de kleinkes helemaole allene achter elaotene. English: There once was a wren who had made his nest in a garage. He lived there with his family. One day he and his mate went out to look for some food to bring their chicks, leaving the young birds all alone.
In addition, each has a history of somewhat separate literature: Asterix has separate translations in each language as does the Bible, and there are websites about them and in them.

All of websites except the Tweants one are of organisations for promoting the languages; the Tweants site is a page with information on Tweants.
