This has been discussed so many times on here lol my opinion remains the same and it is this;
It's obviously subjective to an individual's interpretation but to me friends are friends, online or otherwise. Having online friends in a different category always felt a little undermining to me, like saying "oh you are a friend, but not my best friend." What are we kindergarteners? Friends are friends as far as I'm concerned.
Just like real life though I don't consider everyone I meet or even talk to regularly to be a friend online. I.E there's a dude I talk to a lot at work we get on well sure but we aren't "friends" by my definition. To that end there are people likewise who I just talk to on here or msn etc and have very little correspondence with otherwise and those are also not "friends" as such but just people I get on okay with.
It's hard to articulate my opinion of when someone I get along with (online or IRL) becomes a friend to me but I will say this; if you have to ask then no you aren't one yet. Those who I consider friends know who they are as I talk to friends differently to how I do most other people so you would just "know" if you are one or not
