My story is somewhat funny (well, it still is when looking from a perspective of a 11 year-old).
We were spending a good holiday down Gran Canarias during the new year of '97 / '98 and one of the kids I had become friends with told me his family are going to see one local team play Barça and told me everything about Camp Nou.
At the time my interests were elsewhere and I didn't go to the game, but watched it live in a restaurant, and only then I saw what I had missed. I saw players like Figo (yes, Judas), Rivaldo, Guardiola, Kluivert etc. plying their trade in that Barça side. Unfortunately Ronaldo had left to Inter then, so never had a chance of seeing him don the "Blaugrana". From that time I think I had Ronaldo's Inter shirt, Batigol's "la viola" shirt and old Barça jersey from that season, but Barça was the team that left its marks.
Yet, as the time went by, I slowly started losing my interest in football altogether, mostly because of watching La Liga at that time was nigh impossibility in Finland and there just weren't enough broadcasters doing that, which was the "au contraire" situation vis-à-vis the Premier League. I did follow what was going on occasionally, but nothing more than that. I remember rather dimly the Gaspart era, and some of the players played for the team back then and that it was far from being the most succesful period, which also alienated me from Barça towards NHL instead, which was much more accessible to Finnish audience than La Liga.
However, sometime in 2003 or 2004 when I visited Barcelona for the first time, my interest started gradually rising and only as recently as 2006, a bit before moving to the city, I picked up following Barça again. Since 2007 I've seen prolly 90% of all the games played till now and hopefully will stay on that course forever.
