Hi, Vivienne and all.

I'm not sure that the technique about "same paragraph" is really a 
"sufficient" technique for SC 2.4.4 in most real-world scenarios.

Although the paragraph's text *can* be "programmatically determined", no 
current screen reader *does* determine it and presents it to the user, 
so I would say this technique is not "accessibility supported". Thus, 
IMO an ambiguous "read more" link fails Conformance Requirement #4, 
because the user always have to perform additional actions (and realize 
what to do) to find the contextual information.

In addition, the "hidden portion of a text link" technique is also a 
documented WCAG 2.0 sufficient technique (C7) that has wide 
accessibility support (even with Dragon).

As suggested, I would also recommend to show the complete text when the 
link gets focus/hover (for example, using a tooltip-like style). This 
way, sighted keyboard and magnifier users will have the information even 
if the context is not visible because of a high magnification level.

Regards,
Ramón.

Meeting this requirement would make it easier for someone with a screen reader (and other also).
