I have noticed that many posts about Petra Kvitová use the hashtag #P3tra.
What is origin of this hashtag? Is there some significance to this name (like 3 important wins or somethings similar)?
I have asked this question, but I assume there is non-negligible possibility that it will get closed.
I guess while in beta we will still learn what kind of posts are acceptable and what posts are off-topic. (My experience from some other sites is that evolution of this continues long after beta phase.)
Question marginally related to this: Could creating social-media tag be potentially useful? Or does if fall under media?
