Totally agree, had same experience couple of times, and until now no experience like that of the OP.

BUT: in the 90s I remember saying: supposedly in internet is all and everything, but I never find what I need, is more ads than actual information.

So the I think the point of OP holds. It may (today) not be useful for you, but maybe in some years, and if not, will still ve useful for many people, and is here to stay.

> is more ads than actual information.

This is true now more then ever. Half of the comments in this thread are ads.
