Finding a profile of nice person with common interests is the easy part, I think the challenge in online dating is more along the lines of finding mutual attraction. But I don't mean that to sound superficial. I'm definitely looking for a strong friendship to develop. An ideal partner is someone who is your best friend as well. But I think the vast majority of people want both the friendship and the attraction.
Also, I'm not against making new friends, but I'm here seeking a long term relationship. Only time will tell how a relationship will play out, but I mean to say that I'd rather be potentially on the path to having a partner to share life with, instead of just killing time with someone.
