Again, Jane is going on a trip, here's the picture album, all of that I might want to know about. The fact that she specifically used TripAdviser would only (possibly) matter to me by a coincidence of fate if I am also about to plan a trip of my own.
To put it into cruder terms: if my friend is bragging about a massive dump he took that might be content that I find amusing but the brand of toilet paper he used doesn't enter into it.
Or, another way: If Jane was going to post a status update about her forthcoming trip and had such a great experience using TripAdviser that she would mention it of her own accord that is one thing.
If TripAdviser just managed to get permission to post to her timeline, that's quite another. They are not equivalent by any stretch of the imagination. And while the former is much more likely to get a reaction from her friends, neither are relevant beyond idle chatter to anybody who is not currently in the market for what TripAdviser offers.
