Group similar tips/tricks

It's hard to find what you need in such a large list. I suggest we make sub-groups based on type of application. Like we can have a sub-group, "Places where i can learn?" to contain the many coding/interview sites and tutorial blogs, "Social Networks" for reddit, quora, a sub-group "Networking" to contain polipo,vnc,ssh,sshuttle,privoxy, "Chat applications" for irc, slack, tlk.io.

   What do guys say?

@clearnote01 I mentioned this in the 7th point of the Readme. Thanks for opening this. I totally would like to see the list separated into multiple lists.
The list is already categorized in to some categories already, but that is not good. It needs a revision.
