My grandmother lives in a nursing home where she uses one of the many knee walkers used that the nursing home provides. She is really lucky to live in a place like this that takes care of her this way. Not all seniors are as lucky as my grandmother, though. Most seniors need to get their knee walkers on their own, or ask somebody from their family to do it for them. Every elderly should have an easy access to something as useful as a knee walker in my opinion.
What is most important for readers is to have easy access to information. There are many ways you can present information to readers, and the most obvious one in case of blogs is simply through your website. You work hard on your homepage and you like when people appreciate it. Unfortunately, this might not be enough for some readers, because they have to visit your blog on a daily basis to see if there is something new. That is why RSS and email subscriptions have been invented: they allow readers to know exactly when a new post is posted on your blog. The question is whether you should use RSS readers or Email subscriptions. Unfortunately, there is no easy answer. That is because even thought RSS readers seem to be more convenient, many people are not familiar with them. Technology is changing so fast that many Internet surfers still do not know what RSS really is, and they are happy that they learned about email recently. That is why I recommend offering both RSS and email subscriptions. This way your visitors will be able to chose whatever they prefer. Setting up both subscription methods is not that hard, especially if you look at all of the benefits.
