Only EOY lists from multiple writers are included in the spreadsheets and this blog has only two writers, which was deemed too little for the last year's spreadsheets. However, the blog has many visitors and has received awards and recognitions, so perhaps in this case two critics could be considered enough. There's a Wikipedia page about Gorilla vs. Bear but the notability of the article's subject is currently in question. My suggestion is that when and if Wikipedia decides to keep the page then their lists will be included at AM, but so far they are excluded.
Whatever gets decided is fine with me. It seems like GvB is enough of a known quantity at this point that it probably should be eligible, two writers or not.
