How do you share Web Pages to other apps?

[franzDanconia]

In Windows Phone 8, if you go to Internet Explorer -> Share Page -> Social Networks, there is an option of sharing to Facebook, bu no way of sharing to other apps. What are some of the other apps that can be shared to? I really would like to share pages directly to Twitter and Reddit, and other apps. Has anyone found easier ways of sharing pages on the platform?

Thanks.

EDIT: Here is a picture of what I mean:

Do you have Twitter and LinkedIn accounts set up? Those should work. Post to social networks | Windows Phone How-to (United States)

Additionally, to clarify, this mode of sharing is not sharing with any app - it is sharing with the online services selected. Like Laura suggested, you have to have the accounts set up in the OS of the phone in order to do this, as it is going through the OS to the online service.
