I guess I've been very lucky with omegle. I've had a few mic spammers and dumb jokes, but for the most part I've found some really nice people.
There were a couple of teenage guys hanging out together on the site. I met them and we had a nice 20 minute conversation about the differences in our education systems, and just how wildly apart our two countries were (they were from israel and I'm from Canada). At the end we decided we had had a good conversation and went on our ways. I met a few more people, one who was sharing the apartment they had just started to rent, another who made a few jokes, and then your usual people that click away in the first second.
After I while of meeting new people, I came back to those two guys. We had another fun conversation, then left again. Then we met again, I met the guy telling jokes again, then I met the guys on last time and we added each other on instagram (we got along really well and thought this might be the last time we meet on omegle).
Other days I've had people who made me feel better when I was worried about the future (going out and getting jobs and stuff), people who shared what they were doing for a living with
omegle tv, or just people showing me what neat hobbies they've had.
I've not met anyone bad on there yet, and so far the platform has felt very nice to be on. So many interesting people from all around the world...
