It would be easier to blog about products that you believe in, so for me, if they would join in Social Spark and provide new Opportunities, then I would be very glad to take all of them. Over the other companies that manufacture computer related products such as printers, desktop computers, and the like, in my experience HP products are more durable and more cost-effective.
I'm currently using HP printer and scanner from the HP PSC series and am very happy with the product. I have a friend who has an HP desktop set and I'm amazed by it as well. Maybe sometime in the future HP will sponsor some opportunities. Who knows?
Other companies that I would like to sponsor my blog are music companies such as Island Records; it would be good if I could post blogs about topics I enjoy writing about, like music. Maybe I'd like to have poetry websites as sponsors as well! Writing about poetry would be cool. Anything that involves extra creativity on my part would be cool.
