51. ooVoo
http://www.oovoo.com/

52. Springnote
http://www.springnote.com
Web | Mobile
Use an OpenID, such as your Google sign-in, to access Springnote and you can use this wiki-based site for creating a personal notebook (which you can share) or a group notebook for projects. RSS feeds make it easy for members to keep up, and they can comment on pages when not fully editing the content on them. iPhone users can also access pages via a free app.
53. Skype 4.0
http://www.skype.com
Windows | Mac | Linux | Mobile | Portable
Practically synonymous with VoIP and now with one-on-one free video conferencing, Skype offers its core function—PC-to-PC communication—totally free. That goes for talking to Skype users on smartphones as well. Skype has gotten so big, entire phone systems have been built to use its backbone. You only pay if you want extras, such as the ability to call landline phones or built-in voice mail, but even those are super-cheap compared to what's offered by traditional providers.
