So those of us who want to know how to share a link in the easiest way are probably already accustomed to one or two ways of doing this. When visiting a blog or other web page, you now almost always see a footer or button that reads something along the lines of “share this link,” with a few icons representing the various major social networking and social bookmarking sites. This usually means there’s a Pinterest share link, and an FB share link, and often also a StumbleUpon link too (among other possibilities).

But what about those of us who are heavily involved in social networking and want to know how to share a link to numerous networks at once? Well, it turns out that there are a number of apps and web services that make it easier than ever to share links to multiple sites, and to bookmark links for yourself as well.

Let’s take a look at what these are, and how to share a link using this sort of app. Sites like AddThis.com and TurboBookmark.com have a straightforward interface that allows pretty massive customization of how you want to share your link. The nice touch here is that you can attach your own title to the link, write a standard comment blurb and also make your own list of tags to determine where your link will show up in searches.

But then of course you’ll want to know how to share a link to multiple bookmarking sites. It turns out this is just a matter of checking any number of boxes on a fairly huge list (as many as 42) of different social media and bookmarking sites, like Digg, Google, Slashdot, Reddit and so on. Pretty neat, right?
