Org-mode has clickable links, and they are awesome. You can make your own links, for example here is a link for twitter handles that opens a browser to the handle, and exports as an html link.
(org-add-link-type "twitter" (lambda (handle) (browse-url (concat "http://twitter.com/" handle))) (lambda (path desc backend) (format "<a href=\"http://twitter.com/%s\">%s</a>" path path)))

There is another alternative to make clickable text, and that is the button-lock package. You define a regular expression for the text you want to be clickable, and a function to run when it is clicked. Here is an example.
(require 'button-lock) (global-button-lock-mode) (button-lock-set-button "@\\([-a-zA-Z0-9_:]*\\)" (lambda () (interactive) (re-search-backward "@") (re-search-forward "@\\([a-zA-Z0-9_]*\\)") (let* ((handle (match-string-no-properties 1))) (browse-url (concat "http://twitter.com/" handle)))) :face (list 'org-link))
Check it out: @johnkitchin. Of course, you can make your clicking function more sophisticated, e.g. to give you a menu of options , e.g. to send a tweet to someone, or open the web page, or look them up in your org-contacts. The differences between this and an org-mode link are that this works in any mode, and it has no export in org-mode, so it will go as plain text. Since this is just a feature for Emacs though, that should be fine.
