I swear a lot. Though, it's usually more when I'm excited or pissed off... or fangirling. I try not to swear at places like forums or where it's not really needed and what not. I've been careful about it lately. In real life, I've been cursing some... and my mom will 'joke' by telling me to watch my mouth, which is like... why? I never say things like the F word in real life. If I do, I say it to myself because sometimes it slips out. :x
As for views on swearing, I don't really care. However, if you're only thirteen or something and you're dropping the f bomb to be cool with your friends then... yeah, that bothers me. It's okay for young people to swear on occasion, but it depends on how old you are as well. I don't think anyone under at least thirteen should even try to swear a whole lot. It also depends on how they were raised. Sometimes, they hear it from their parents and repeat it. Then, the parents always wonder where they picked it up, not knowing they were the ones that had said it.
My mom said dammit a lot when I was really young too. So, one time I was at my grandmother's house. I got frustrated with my shoe, threw it to the ground and said "dammit" because I had heard and seen my mom do the same thing. It was actually kind of funny at the time since my grandmother looked at my mom like "wtf?". XD
