I was walking in a park at morning, see dew on leaf so I write down a note in my mobile that my blog name will be start from "dew..." then next day I research on google for domain suggestion and finally decided to use "dewlance" for my blog name.
It was take at lest 10 hours in searching on net and after 2 month in August, 2009 I was decided to use my blog domain as a brand name.
