I kind of observed to myself that very small ant colonies, you can pretty much treat each ant as an individual and it makes watching them easy and interesting.
However, once they reach about 500, even more over 1000 or 2000, they start to act like a liquid (at least when kept in an enclosed formicarium). It is a liquid that is always trying to leak through the smallest gaps.
Once they hit about 2000+ they feel so much like a semi-intelligent, hungry fluid they creep me out a bit. I try to keep my larger colonies bonsai'ed to about 1000-2000 max.
