Appreciate the kind feedback, and it's never too late to learn: I'm 10-years your senior and have been able to figure out some of this on-line stuff, albeit I'm still basically a hack.
To your needs, Blogs are indeed searchable, by key words (upper right hand corner of my Blog) or by using drop-down menus like the ones in the right-hand margin of my blog, i.e.,
Archives: Select Month
Categories: Select Category
The problem with hosting the entries off my Website, which I did from 2001 - 2009, is that it's very hard to find anything other than using Google which may or may not produce what you're looking for. There are thousands of updates in my web archive, which are about as hard to find as the 6,500 things that I've posted to BikeForums over the years. It's also a lot harder on me since I have to manually upload those entries.
The Blogs are more like an on-line diary that lets you easily embed images, links, videos, etc... so that everything can be archived, searched, and found in a number of different ways. I'm somewhat surprised at just how many Google searches outside of my Blog or site turn up results from my Blog. From a user-standpoint, the Blog is much easier to use for composition, editing and publishing and it links to FB and other on-line resources, if you so choose. I like the Blog format mostly because I like to publish long, content-rich articles that really don't lend themselves to most other formats. It also saves readers of those forums from having to deal with my typically longish writings. But, most of all, I write about what I strikes my fancy without forcing it upon anyone; it's an on-demand publication for those who find what I write to be of interest, value or perhaps a nice distraction. To the rest of the world, it's pretty much invisible.
Mind you, the Blog doesn't replace my Website, it's merely an adjunct to it since all of my rally calendar info, tandem club listings, and other links still reside on www.thetandemlink.com. There are a couple of links on my Blog that take readers right to those and, likewise, links on the web site that take surfers to my Blog.
At the end of the day, Blogs seem to work best when you simply find one that consistently has things that are of interest to you and that you subscribe to so that you get automated feeds when something is posted. If the subject catches your fancy, you read it. If not, you don't. Its very similar to being a subscriber to mailing lists like Tandem@Hobbes or forums & threads at BikeForums.net, but far more specific in that you know exactly who's doing the writing. I have my own small list of Blogs that I follow as well.
