You want to find a specific blog post about a specific product, but Google gives you a list of useless search results!... I think pretty much everyone will understand this problem, so Ian Hedley, the man behind the great blog: Pens!Paper!Pencils! has created a useful Search engine called 'Pennaquod'.
Pennaquod only searches for results within a specific list of pen blogs, so you'll never get irrelevant results!
Currently the list of blogs is still small, but the results I got are already very good, accurate and fast! Be sure to go check it out, and give Ian a heads up if you have a pen blog that isn't featured yet!
