I am and I can tell some fellow bloggers are as well, ( I see the ad I was solicited with in their post.)
I have to say it bothers me a bit. I do like to post about products I actually use, love, admire, notice...
I don't like being used by manufacturers or businesses to shill their products when they aren't even sure if I am aware of said products.
Even if they did the right thing and sent me a sample or wrote a personal email (rather than the usual "preppy style" form email with 30 other names on the mailing list) I would feel duplicitous and manipulative in regard to the people that read my blog.
I am not holier than thou. If an amazing product came to my attention and I actually liked it, after receiving a sample of course, I would promote it!
Until then, when I receive unsolicited requests to promote products...
I will hit- delete.
What do you think?
