I finally know where to get the common icons i see around in the internet like… 
or 
and many many others… here are some of the links where we can download and use them :P i think this list of icons would be really handy for blogging or even web designing.
- FamFamFam Silk icons (my fav!) and other icons.. i got to know this from Becca
- Smashing Magazine’s list of stock icons and other symbols and buttons (my fav blog :D)
there you go!
