Hm, but if i search something without the "#" i also get related results.. It just looks stupid that's all, majority of tweets now are like "RT@tiesto, i #love #life, @howawesomeislife"
C'mon..
But i agree though, i really started to see the use of Twitter..
I know, you can search without it. You can click them however and it takes you straight to the page! (yes, useless) Still, it is easier to search for tutorials with #PHP than with PHP since other people talk about PHP and I am not interested in that.
