Yes, the execution when it comes to self promotion is very important. No association, but I really like this answer[0] from CloudSponge, saying why their product is best on a thread asking for alternatives. What could have been very slimy comes across as genuine and helpful. It nearly converted me to a CloudSponge user when I came across the question while looking for alternatives.

Since he was invited to answer the question, I immediately assume the question itself was planted.

Seems more likely that someone in their PR team saw it and invited the him to answer, no?

Interesting idea though. Consider me out-cyniced

I remember when I was so harshly cynical like this. It was absolutely exhausting.

this is pretty much what I've done in for my startup http://documize.com but seems like Quora is bashing down now on any self promoting outgoing link, I think they are now under pressure to make more revenue from their ads
