The workaround that I use is to bookmark the "Find More Posts by _____" link for everyone whose posts I may want to follow. I believe the Internet Explorer term is "Add to Favorites".

It's not a one-step process, unfortunately. If you actually click on the "Find More Posts" link and try to bookmark the search results page that comes up, you'll find it has a short shelf life. What I do is copy the URL of the "Find More Posts" link to my clipboard, bookmark whatever page I found it on, find the bookmark I just created, right-click on it, and choose Properties. I make sure the bookmark title says what I want it to ("Posts by _____"), then tab down to the URL field of the bookmark and paste in the URL that I saved to the clipboard earlier. The procedures for Internet Explorer and Apple may or may not be similar to this; I've never tried working with bookmarks/favorites in either one.

The kind of URL that's only temporary and not worth bookmarking looks like this:

The kind of URL that you want to end up with in your bookmark looks like this:

Both of the above examples use made-up numbers, by the way.
