crazyguyonabike.com: Bicycle Touring: A place for bicycle tourists and their journals works fine for me and those who care. I was able to update every day or two from public libraries using public computers--I carried no electronics at all, not even a phone.
You can go overboard. I met a guy on tour who was stressing over getting to a motel with internet every night so he could update his blog, upload photos, etc. to keep in touch with his "audience." I checked out his blog and it was pretty sad--full of misspellings, bad grammar, pretty lousy photos (he even included one of me and who cares about that?)--gadgets and wifi don't make you a good writer/photographer. His blog had very few hits, just a few family members it appeared.
