Do you keep a list of how many anime series you've watched?

Not only do I keep a list counting all the different distinct series, but it's in chronological order, so I always know the first, the most recent, and everything in-between in the order in which I watched them. I keep it as an actively updated running list on my profile page, and include some basic accompanying information like the genres for the series as listed on MAL and another online resource (either Wikipedia or Anime Planet, depending on whether Wiki lists it or not), as well as my personal rating out of 10.

The criteria is that I don't include films or standalone short films (but do include series with as few as two episodes), don't include currently watching series, don't include paused/on hold series, and don't include dropped series. Otherwise, if I did, the total tally would be a lot higher than it is by dozens. And I include a series on it and consider it counted as long as I have watched one full season of it. Most of the series on it I have watched all the seasons of or they only have one season anyway (however long in terms of episode count), but I make that statement because there are series which I watched one season of and don't have a wish to continue and watch the other or others right away or at all ever. If I'm planning to continue watching the seasons one after the other pretty much back to back then I'll wait until completely finished to add a series.

Anyway, that list as it presently stands is at 296. I already know what my 297th and 298th series will be as I only have a few episodes left in each of them. But then there is 299th which I also have a feeling I know which it might be, and then it will be very interesting to see what ends up as my 300th, either randomly or if I decide to actively choose one for that distinction.

And even if I consider the one I mentioned on my profile page on MAL as like the original or "master copy", it's technically not only limited to MAL, as I have the same list on some other websites which are for listing and categorizing multiple mediums of media, as well as offline on a Notepad file and Excel/OpenOffice-type electronic document in case MAL or any or all particular websites were to go down.
