It is always a simple matter to just hit the top link bar in order to read the entire article which is what I usually do anyhow.
It is a simple matter... unless you're on dialup (and folks still are) and the site is larded-up with graphics and other slow-loading material. When I still used dial-up, "excerpt" meant I was not going to read the article unless I was really, really, interested enough to wait many minutes for the garbage to download.
Even now if it's excerpted, it's fairly likely I won't click through; it it's presented in its entirety on FR there's a fair chance I'll read it.
And what of the brand sites that permit no excerpts, links only? And I think in this internet world there are sites that complain if they are even “deep linked” to (sending someone to an article rather than the front page).
At what point is it impossible to dispute what a so called “journalist” has written into the historical record because you cannot quote their writing?
