My own blog

// March 16th, 2005

This is my ‘very’ own blog with paid hosting ( Rp 250.000,- / year) , my own domain ( Rp 165.000,- life time ) and much more controllable wordpress. Of course this will decrease my ‘norak’ level.
I will post in english in this blog just to force my self to use better english in my everyday life. My english is very poor now , I hope with people help it will improve in the mean time.
My older blog at blogger still could be found at blogger category , while blogging category is my notes all about blog.
You should has a question why I use ‘lensa’ (lens in english) as my domain. Lensa is an acronym of my mother village which called Leongan in the city of Salatiga when I am a child. Now it is changed to Margosari , I don’t know exactly why people change the name but I still like the older one. And I use elangmaya as a nickname because it’s cool isn’t it .
