قدم دوم این است که برای اینکه مسوولین پروژه بتوانند تصمیم بگیرند که با چه کسی کار کنند، می‌خواهند نمونه‌ی کارهای علاقمندان مشارکت در این پرزو‌ه را ببینند.

- -

برای همین از همه‌ی علاقماندان، حتی کسانی که قبلا اعلام آمادگی نکرده بودند، می‌‌خواهم که یک موضوع رایج این روزهای وبلاگستان فارسی را انتخاب کنند و در هفتصد کلمه، به انگلیسی، بنویسند که وبلاگ‌دارهای درباره‌اش چه می‌گویند. لینک به پنج، شش وبلاگ و بازنویسی آنچه آنها از جنبه‌های گوناگون درباره‌ی آن موضوع نوشته‌اند با نقل قول مستقیم از آنها (البته ترجمه شده از فارسی) کافی است. دو سه جمله هم اول کار توضیح دهید که چرا این موضوع مهم است.
