1. Eredivisie (Holland)  2. J League (Japan)  3. Ligue 1 (France)    

1. MLS (USA) 2. Ligue 1 (France) 3. Scottish PL

Followed immediately by Eredivisie (Holland)

I mentioned before the Brazilian, Argentinian, Mexican, Portuguese, Russian, Ukrainian and Turkish leagues, but it is very unlikely for me to follow them. There is only so much hours in a man's life

Sometimes I think I follow the Championship League in England more most of the Euro leagues out of the Big Four

I only "follow" the league that my team is in, everything else is just something I watch.    

Primera A (Columbia) and the Jupiler league (Belgium). Maybe the Austrian Bundesliga if I have the time.

I don't follow these religiously, but you know. I keep my tabs

I follow closely the French Ligue 1 as well as the Portuguese Liga Sagres.
I also watch highlights from the Eredivisie, Brazilian Seria A, the Argentine Primera Division, Colombian and Uruguayan leagues.

Also:

The Turkish and Greek Superleague, love the Derbies and Big Matches

I mostly watch EPL (Spurs games + derbies, big 4, etc.). Bundesliga is the second one for me, and La Liga comes third. I watch a bit of Eredivise, as well. On footytube, I like to catch up on Russian, Seria A, MLS, and derbies from Ukraine, Turkey, Portugal, etc. One league I almost never watch is Ligue 1, they bore me to death! Not a big fan of Serie A either, but I don't mind watching the big matches

Dutch league, brazillian league and mls

A league, Eredivisie, and French Ligue. Oh yes and the championship

MLS is about the only other one I follow - Bundesliga, EPL and La Liga are good enough for me although now and then i'll check out any one of the other several leagues out there
