Well, initially I started off by having a friendly competition with a senior of mine (both of us FOSS enthusiasts) after noticing my own inadvertant-streak. At that point it was less about vanity and more about competition and fun. Of course, when I reached 50 I was more than happy to boast about it :P At this point -- keeping it up would be mainly a vanity thing (but I'm not consciously doing so). For the past few weeks I haven't even thought about it unless I open my profile and notice ("has it been that long? Wow."). It's just continued with no conscious support -- I used to sometimes think "hey, did I forget to commit today" (the answer would usually be no, but the point is that I was still asking myself this). Now I don't. Not because I know I've committed, but because the streak doesn't matter.
