i find blogging useful because..
of the free credit i get.
That very credit i got i effectively used it to purchase photos which my friend needed for her project. I need not convert any earnings yet I am still able to help out by providing the picture as needed by my friend. While I cannot create the picture she wanted, Dreamstime offered the picture at such a low price with great quality.
well, here's thanks to DT's blogging feature!~
