I met my husband in a parking lot at a festival. He liked my butt, I liked his beard. Married 18 years now.
Other (less) Significant Others - one I met at a friend’s house, the other at the old Castle Dracula show at Universal Studios (in 1980, for those who remember it).
Never met anyone of importance at a bar, club, party, agency, work, via blind date or otherwise. Always a big accident.
We met at a fundraiser for the local public library. I was a longtime donor of money; she was a volunteer for the event.

The Internet!
And this was in 1998.
He crashed a friend’s birthday party in a gorilla suit.
The chart in the middle of the page may be helpful to you (or, er, not).
We’ve been together nearly 18 months!
Same here - college, friend of a friend of a friend kind of thing.
College friend and post-college housemate of my sister.
Dude… you can’t just leave it at that!
Met her on the ferry going to work. We were friends for awhile–and eventually started to date and have been together now about 4 years, married a little over two. I do think being friends first helped the transition. One day we were friends and then suddenly we both started looking at the other person in a different light and eventually our friendship was more like dating and then there was no question about it. We were in love. Still very happy and am glad I asked her that one day what she was reading 
He likes running around public places in a gorilla suit. I swear one of these days I’m going to have to rescue him when a rent-a-cop catches him.
The first words I ever said to him were “Looks like a stupid monkey,” because I thought he was my friend Terry. Terry showed up minutes later. Ah, oops.
One of my room-mates at the time knocked him over from a running start and stole his mask. He ran off until one of his friends got the mask back.
Later, he had a crush on another room-mate of mine (I had four then), but she was interested in someone else. I “stole” him. Oddly, she was a little upset about this.
Roommate (who I hated and was a complete bitch most of the time) had her friend spend the night. My computer was broken that week so I had nothing to do. My roommate went to bed early, so me and her friend stayed up the next two nights “watching movies”. Started officially dating the following week.
28 years ago last February 28th, in a small bar in Berlin, “Dreizehn” (translation: “13”) - a bar that a friend had recently opened, I saw a guy and our eyes met across a crowded room.
Prior to that I was a male slut, but from that day on, I was a happy Gay man with a life partner.
At the Metra station at 53rd St., Chicago, in July 1993. We got married five years later, and we’re still going strong! 
(Not that I would recommend train platforms as a pick-up spot.)
I met my SO at sleep-away camp. We were 10.
We didn’t start dating until later, though.
Craigslist (the dating section, not the casual encounters section.)
At work. We worked together (very closely) for eleven years and were quite good friends before we figured out that we should take the next step (went pretty quick once we figured that out). She was married for the first eight of those years, so we have an excuse for waiting as long as we did…
eHarmony.
The wedding’s this fall.
We were inner-tubing down a river on a hot summer day in San Marcos, Texas. Our tubes drifted by each other and we started talking.
Married over 12 years and 4 kids now.
Church. We knew each other since we were both young, but since she’s six years younger than I am, there was no real “dating” vibe at the time. Once we were both a little older and we started singing in the same quartet, though, we got a little closer. It’ll be 11 years in June.
I have no SO, because I hate the drama too much. You’re right about the workplace being a bad venue, but the only way to avoid drama is never to get involved with anybody. You reap in happiness only what you pay in heartache.
