Twitter please deal with shortened urls...

So this is a pseudo-rant that really isn't a rant, but this is really annoying me. Twitter doesn't resolve urls when they are presented in the twitter interface. This is really annoying. Why you ask?

1. Well for one I am never sure if one of my friends is posting something from their own blog, or some other place I am interested in, or they are posting about something completely unrelated/unintresting. I know, I know the message is supposed say something about the url, but it doesn't always, and it certainly doesn't let me eliminate sites I don't like (say I don't like Mashable, not true of course, I can't know that one of my friends just posted a Mashable link).
2. It is huge security problem. The links are anonymous, so we have no idea where they go. As a web professional I can identify some weird links just from there look, but perhaps more importantly I don't think many of the automatic url scanners in the browsers (for phishing, etc.) actually resolve the url to its source, and therefore don't identify malware sites which have been shortened.

So what should be done... Very simple, for every url that gets posted to twitter they need to do a HTTP Head, and resolve the url to it's source (re-searchr does this for most of the shortened urls it sees). Yes this is another step. Yes it is more load on there servers. Yes it still should be done. Note this will NOT effect the 140 character limit, use as short a url as you want in the message, only when the message is displayed should it be expanded.

The other half of this issue is for the Twitter search, try doing a search for http://www.techcrunch.com on Twitter's search engine. You'll find many fewer results than there really are... that is unless you start getting the shortened versions of the Techcrunch url. Before you say, well okay I'll get the tinyurl and bit.ly url and a few others and be done with it (and with the explosion of shortened url services, good luck with finding the best shortened urls to use)... Twitter search has a 140 character limit, so good luck doing more than 2 shortened urls. Additionally good luck doing a wildcard search for http://www.techcrunch.com/* to get all techcrunch posts urls as well, this is impossible with these anonymized urls that hide the actual url structure.

So there is my rant, and my evidence, let me know what you think either in the comments or @jostheim on twitter, but for goodness sake don't include a shortened url!
