Touch - Back to the Matchstick Puzzles
Place six matches in such a way, that each match is in touch with all the other five matches. Notice that it is possible with 7 matches as well.

Place them in spoke (bike) arrangement, possible with infinite sticks as well!

that would almost be right, except that all objects have width. a spoke arrangement would only work assuming no width (like pencil lines). try putting 5 pens in a spoke arrangement, there's no way all 5 can touch each other perfectly.

Why not arrange them in a pyramid? I think that would do the trick and be much more elegant?

Looks like touch2solution.gif shows 7 matchsticks (pencils). Pretty impressive.

Sorry, a triangular pyramid would not work, because every match would have an opposing match not touching. These opposing matches would be skew: neither parallel nor intersecting (and thus not touching).
