I was told that we can not consider the website Wikipedia as a source of reference .
Is that right?
The second question is :
Is the Algerian a dialect or a language?
To me, they're two languages if they cannot be mutually understood by ordinary speakers without specific education in the other.
Wikipedia is a wonderful resource. I cannot now imagine life without it. I use it several times a day, every day of the year, but it has no value as a source of reference. We have no idea who edited the articles last. It is magnificent for finding information quickly and efficiently and, given that obvious misinformation is usually corrected within minutes by self-appointed editors, the information is usually accurate and very up-to-date.
But, you cannot quote as a reference an article that may have been written only ten minutes ago by the eleven-year-old thug who lives next door to you.
