To be honest, anyone who wants to be nerdier is probably as nerdy as a person can be. Which is a good thing, an excellent thing actually. But I will list some things that most nerds like doing.
Video games.
Reading/Writing.
Politics/Debating.
Being awesome and telling others about the awesomeness of nerdfighters.
Making video vlogs/regular blogs.
Random other stuff that decpticons (popular people or non-nerdfighters) dislike but nerdfighters are assumed by.
Most important tip for nerdfighters: Be Awesome!
There is obviously many more things that can be added to this list, but I can't think of them all at the moment. If anyone knows one I missed go ahead and add it.
One aspect of being a nerd comes down to actually caring about certain things in detail and not caring about what other people think of that level of caring.
The fact that you actually spent the time to create a thread for nerd tips is pretty nerdy in and of itself, so good start.
Not to be repetitive, but improvements on spelling and/or grammar will help. I obviously know you can spell "help", but overuse of misspellings to sound clever seemingly only works for lolcats/lolbooks.
Jeez, don't I sound like a condescending bitch! Sorry!
