At least here in Colombia we use 100, 200 and 500, which I find better than 25 which is basically a glorified prime number (you can root it and then no more division!)

But in all seriousness, I don't think we should use coining systems for milestones but rather I believe every 10,000 articles or so are a rather important milestone by themselves. And it's nice, round and even.
