You may have heard that Apple has about $110 billion in cash reserves just sitting around. You may also have heard that, if converted to dollar bills, this money could fill about 50 Olympic-sized swimming pools. You may be hankering for some more hastily-calculated, hilariously meta statistics about what else Apple could do with $110 billion and Olympic-sized swimming pools. You want statistics about money and swimming pools? We’ve got your statistics about money and swimming pools.

Everybody loves money, but you know what everybody loves even more than money? Statistics. OK, maybe that’s just me. In any event, tonight there is going to be a drawing for the largest Mega Millions Jackpot — the largest lottery jackpot in general — in history. It’s reported, at the time of this writing, to be a whopping $640 million dollars, or roughly the net worth of Facebook co-founder Chris Hughes. You can win your own Facebook co-founder(‘s net worth). Of course, your chances of winning are minuscule, a nice 1 to 175,711,536 or a .000000005% chance. But what fun is knowing that if you can’t put it into perspective against a bunch of wacky things? Every self-respecting blog should have a list; here’s ours.

Want to know why people are unfriending you on Facebook? Well, it’s not as easy to tell as it was back when everybody was doing it for the Whoppers. Sometimes you just know, but other times the best you can do is venture a guess, and this infographic from NM Incite can help you narrow it down. Most of the time it’s due to offensive comments, or the fact that you were never real friends with people in the first place. But you can also get cut off for updating too frequently or too infrequently. If it makes you feel any better, “physical attractiveness” and “increasing friend count” rank 4 and 5 on the list of reasons to friend people in the first place, so you’re probably better off with fewer friends in that case. Or, at least, that’s a good thing to tell yourself if you need to sleep at night.

iPhone versus Android: The eternal mobile battle. There are a lot of ways you can come at the competition: Which has the better hardware, which has better customization options, which has the better software and development capabilities, which one has the least annoying fanboys, and one more: Which users have more friends? And that is what this infographic courtesy of Onavo tackles.

Okay, not really who has more friends, but rather, who uses which social apps and how. But that’s totally the same as who has more friends, right? It’s not like anyone ever just uses social networks to self-promote or pester people they don’t really know with details of their life that no one reads or cares about. No, social networking is all about maintaining deep, involved relationships. Definitely. But the iPhone has 27% more Facebook use, so those guys must be more popular.

Facebook is big. Really big. Like seriously, it’s huge. So huge in fact, that it now has as many active users as the 2004 Internet. That’s right, there are as many active users on Facebook as there were active users on the entire Internet in 2004, the year Facebook was born.

Folks at Royal Pingdom were the ones to figure it out based on the f8 statement that Facebook currently has over 800 million active users (active users being users who have signed in in the past 30 days). It’s also worth noting that Facebook has more users than the Internet currently on every continent except Asia, and more users than any country, which is a little less surprising. Still, it seems like Facebook is still on its way up somehow. Where will it stop? We’ll probably find out when the Apocalypse arrives.

Check out some graphs breaking down the numbers after the jump.

Mobile devices have made it much, much easier to goof off pretty much everywhere, in class, during a conversation about “where this relationship is headed” and most of all, at work. This infographic by Column Five and Wistia looks into the mobile-video-goofing-off phenomenon and figures out the numbers, at least as far as Americans are concerned. While it’s not entirely surprising how many people view mobile videos at work, you might be surprised the ways in which some of them go about it. I’m just glad trying to dig up viral videos is part of my job.

Christopher Finke, the creator of URL Fixer, a browser add-on that fixes typos and generally smartens up the address bar, has been collecting anonymous usage data from the people who use his add-on for about six months now. As a result, he’s amassed 7.5 million inputs, a respectable sample size, and used them to come up with some statistics that he posted on his blog, where he writes about things he has done. He brings some interesting information to the table, and while it may not be pratically applicable in any way, it certainly is fun to read and then spit back at your friends.

Here’s a few little highlights you might be interested to know.

• As shown above, the top 10 URLs account for 20% of all typed domains, and Facebook accounts for 9% on its own, 3 times more than runner-up Google
• Faceboook.com is the scammiest typo URL (you’re a Facebook winner!), but is only typed once for every 7,930 correct spellings
• The most common top-level domain (.com, .org, etc.) is .com with a whopping 63% to runner-up .org’s 4%
• The top 17 TLD typos are all variations of .com
