I don't profess to be much of an expert on fancy analog writing tools, but I do enjoy drooling over them now and again. I typically rely on internet friends like Brad Dowdy and Patrick Rhone for information and tips about such things.
Pennaquod, a Google search tool put together by Ian Hedley, allows you to search over fifty (!) of these pen blogs at once. If you've ever wanted to know about particular fountain pens or notebooks or even typewriters, bookmark this super-handy site for later.
Fair warning: that site is a gateway into some deep, deep rabbit holes for even the most minor of pen nerds. Tread lightly.
