I think it is actually just a trendy way of saying "an example", but one may think that by "nosto" the speaker/writer wants to suggest that this example is a "good pick" among available examples due to its quality: it may be especially interesting or illustrative, or it may present the most typical or essential features of the subject matter, making the "nosto" well presentable. So, not just "an example", but "a good pick", "a noteworthy example" that helps the audience to better grasp the essence.
