I chose to use both Academia.edu and Linkedin for my online profile.  I had an Academia.edu profile that I set up last year, and really like the user interface, but I realize that Linkedin is probably the more recognizable of the professional profile builders, so I used that one as well.  I ultimately feel Academia.edu is probably better for me as a student, since it allows for projects and scholarship interests more so than Linkedin, but I will probably be more visible on Linkedin.
