Yes I do. I think it is an implied question at the end of a statement asking the other person in the conversation to convey their agreement with or understanding of the speaker's utterance. This demonstrates the speaker's lack of confidence in their thoughts. An assured speaker will make concise statements, linked arguments and even rhetorical questions (constructed as questions) to explain their position.
Whilst we are on the subject of annoying speech trends, let's attend to the mainly youthful use of the word "like". It is used as a preposition, but in a meaningless way, for example, "When I asked if I could like stay for a while, he was like dunno. Can if you want to". I think this use also demonstrates the speaker's insecurity, and invites the listener to draw similarities to the situation or idea being described, thus introducing vagueness so no criticism can be leveled at a poor description. It might also be a gibberish word inserted to allow the speaker time to think whilst remaining connected with the listener, other examples being, "er..", "you know", and "ahh..".
