Anyone ever click on url's in the tweets of those you follow on twitter?

Tweet

I don't pay much attention to the tweets tweeted by those I follow on twitter, let alone click on the url's that are included in their tweets. Is that not propper "twitter etiquette?" I don't deliberately ignore the tweets of my fellow twitters, it just seems like a lot of spam to me. When and if I tweet anything, it's usually just a status update of some kind. Very rarely do I send out tweets with links in them, but every now and then I may get a tweet specifically targeted at me with my @twitterusername on it, and since twitter cloakes the url to into a tinyurl or bitlyurl you don't really know what kind of site it is other than what the tweeters description is, which is usually masked itself in order to get you to click on it. Is it just me, or has twitter seemed to turn into a spam fest?
