In Algeria, Kabyle is taught in the latin alphabet (schools/university). All experts in the kabyle language use the latin alphabet (mouloud mammeri, salim chaker, inalco, académie berbère...etc), and all kabyle websites who write in kabyle write it in the latin alphabet. (www.imyura.net or tamazight.fr for example)
All those who are willing to participate have studied the grammar of the kabyle language in the latin alphabet (including me), so obviously the kabyle wiki will be written in latin.
But if you want me to develop some arguments on why we prefer the latin alphabet over the tifinagh or cyrillic or chinese or hebrew or eventually arabic alphabet, here they are:
-We are a little people of 3 millions in Kabylie (6 if we add the diaspora), so we choosing the most practical solution : the latin alphabet. Just have a look at the kurdi wikipedia which uses the latin and arabic alphabet, 99% of the articles are in the latin alphabet, and less than 1% are in the arabic script. Also note that the number of kurdi-speaking people is the tenth of that of the arabic-speaking people but the kurdi wiki have more articles than the arabic wiki, add to this paradox the fact that 99% of kurds never studied their language because the states where kurds live do not promote the kurdi-language. facts prove that the latin alphabet is much more practical and efficient.
-Modern Tifinagh works exactly like the latin alphabet, it is written from left to right and has vowels, so it is easily convertible to latin with the use of a software (it would take less than one second for the whole process). but as I said earlier we seek efficiency in both real world and internet. No one's going to read the articles in the tifinagh alphabet... and especially write them on a paper. I have an experience of 5 years writing with the tifinagh alphabet, but still, it takes about 5 seconds to write a word in tifinagh but less than 1 second in latin. (don't forget that tifinagh dates back to 500 BC, so the letters are very primitive, very big, and complex to write.. I'd say draw since they look like geometric figures). Trying to improve the tifinagh would mean creating a new alphabet, sincerely we do not have the capacity. Also, "improving" means that it (tifinagh) is used, which is not the case.
-As for the rest of the remaining scripts, I wonder why we would use them since we don't even use the one our ancestors used. Moreover, 99% of newly written languages are in latin alphabet, that's because it is the most efficent. Do not get me wrong, I respect the chinese who wants to keep using the chinese pictograms, it's good that they keep an ancestral tradition but I'm not going to adventure my language which is very, very weak into more troubles.
-some say that because Berber works like other afro-asiatic language, by knowing the grammar and some practice, you can guess 90% of the words' vowels, therefore it should use the alphabet used by other afro-asiatic languages. This is also the case for english :
"Many non-Semitic languages such as English can be written without vowels and read with little difficulty. For example, the previous sentence could be written"
"Mny nn-Smtc lnggs sch `s `nglsh cn b wrttn wtht vwls `nd rd wth lttl dffclty." (example taken from wiki)
but I care a lot for the remaining 10%. the second sentence looks pretty much primitive if you ask me. Also, not all afrasian languages use hebrew or arabic alphabet, for example maltese and ethiopian use the latin alphabet. Speaking about maltese... there 1000 times more arabs than maltese (300 millions against 0.3 million), but the maltese wiki has half the number of what the arabic wiki has as articles.
-I hope I have answered your main question, and most importantly anticipated your eventual replys.
