Contribute something good ? What do you think I am - a philanthropist ?
I am here for a singular purpose that I excel at - Trolling !
And trolling is an extremely positive contribution in and on itself, if you must know !
It fosters harmony between diverse and varied communities on PDF many of whom don't like or agree with each other and in the midst of all that chaos and disunity I stand, with my trolling arsenal at disposal, as a beacon of peace, harmony and fraternity.
Yes..I - the Great I - who steps in every now and then to break the ice, to diffuse situations, to keep trolls in check (counter-trolling is, after all, an important skill too) and spread love, happiness and the betterment of all men regardless of caste, creed, country or culinary prowess !
OMG...I am so emotional right now !
