I often select text in articles as a visual cue which line I'm reading.

Why oh why does this site needs to pop up a "share" widget when selecting text?

Websites are really popping these "share" things all over the place lately.

Maybe the websites are lonely?

Use something like Evernote Clearly. It presents the content better and you will be able to select text without the widget popping up.

I'm with ya. Select, scroll, know where I was.

Just disable javascript for this page. (in opera at least)
