Posting to explain my selection - 'half the time'. I feel like there's a bit of difference between RPing in linkshell and RPing 'face to face'. My char is rather socially awkward and prone to roaming since his job requires first-hand travel experience. So, I RP in linkshell more than I RP face-to-face, since this supports my playstyle anyway. If LS RPing counts, I'd hop straight to the high end of 'often'. Though that being said, I do consider myself in-character nearly always - if someone randomly strolls up to me and starts RPing, I'll almost never say "Sorry, I'm OOC right now" and I tend to avoid /saying or /shouting OOCly.
If I'm online, chances are I'm doing leves until a bit of RP catches my attention - I tend not to go actively hunting for and asking about it unless my "to-do" list is checked off, but I'll almost always roll by for some RP if I spot it and it'd be character-appropriate to hop in. Sometimes I'll even roleplay in LS as if Verence is doing something I'm not actually OOCly doing if it makes more sense for him. I try to keep that to a minimum though, since Verence is so easily distracted and far-ranging that it's not hard to see him doing just about anything on a lark.
Anyhow, long answer short: If LS RP doesn't count, Half the Time. If it does, Very Often.
