This is reasonable, but be aware that this signals a particular type of qualitative data analysis. For some analytic strategies, e.g. ideal type and narrative analysis, context from which any particular passage is drawn will be hugely important. So treating quotations "clinically" will work for some strategies, but certainly not for all.
I meant to convey that the context would come from the talk itself (where you can read more quotations than a slide) and from the analytical framework. I don't know what ideal type and narrative analysis are. Can you explain?
Sorry, don't read too much into what I wrote. For a talk, I agree with others that a snippet of text on a slide and reading longer quotes makes sense. My point, I think, was more a reaction the language used by 1dd0 and was probably more appropriate for another thread.
If you're curious, here's what I meant (although this won't have bearing on your presentation): Sometimes the way a person tells their story is a finding in and of itself, so it's necessary to present longer narratives. Or instead of using snippets from a bunch of different Rs to illustrate a point, sometimes scholar will use one as the "ideal typical" representation of their category. That approach to data presentation is more, "here's my point and here's a person that illustrates it really well." With that approach, it often helps to include a % of how many other respondents fall into that category. One nice example of this (in text, not a talk) is Jennifer Silva's 2012 ASR. Hopefully that's clearer!
