As I'm sure you know, the topic isn't about internet facades. So please gay it up or take it to PM. Good thing you did -it took me a while to write this-. -- Now, returning to the topic, self-identifying as "bi" might be a step of sorts for some people, not as part of a transition "towards", but during self-discovery and acceptance. When the fact you like people of the same sex stares at you in the face and is unavoidable, claiming you are bi allows for some honesty while people still try to cling to a false heteronormativity ("If I am bi, maybe I can still marry a woman", etc). Sadly, that makes people doubt about the real bisexuals are there. That being said, experience tells me that people who say "bisexuality is more natural" or "everyone is a little bit bisexual" are usually the bisexuals themselves. :P
