Why I am unsatisfied by job search websites

So, I'm currently unemployed. The current economy being totally shit does not help this matter, but I am not here to discuss that today. Rather I am here to trash all the job search sites I have used. Specifically I am going to say how bad the sites that are only job search fail at their tasks. I will discuss the sites I have used one by one.

1. Craigslist: This site actually works well for what it is. It does not claim to be a full featured job search site, it is free, you don't need an account, there is no screening of employers or prospective employees. The search actually works well, it's easy to check different locations, job types, and narrow the search. Unfortunately there is no saved search or anything like that (it would actually be pretty useful for craigslist as a whole), but for doing period searches by hand it is pretty good.
2. Monster.com: This site is a dedicated job search site, and to apply for a job you have to sign up for the site. However, rather than being more convenient than say, craigslist, it is much less. There are a great variety of annoyances, but the one that impacts my finding a job the most is that the search function is terrible. It has a bad interface, and once you spend 10 minutes configuring it right it does not save properly. I graduated from college in June, and it keeps sending me senior developer positions. There are also a lot of adds, including obtrusive ones for the university of phoenix (I've got a BS, I don't need another). Overall the site feels like it was written in '98 and could seriously use a refresh.
3. Career builder: This place is on average about the same as Monster.com, but has different annoynaces. The save search still is crap, but there is a "jobs similar to ones you have applied for" search that works decently. On the other hand it was a huge pain to sign up for, I had to put in my info at least 3 times because it kept going to the next page of questions before I was done, and then when I went back to edit it everything was wiped out.
4. Usajobs: This is the official US government job search site. It works ok it's self, but the jobs are posted here in a very annoying way. Not only is the language of the posting strange government legalese, but there are huge numbers of the same posting repeated again and again. Also to apply to many of these you have to go to another site which brings me to my next section...
5. Company or agency specific sites: These are by nature hugely varied. The worst are government sites, one of these I could literally find no way to apply. Boeing has a good one (the saved search actually works).

Someone should make a website that aggregates the search results from a variety of sources and consolidates them so that you don't need to sign up for all of these places just to search, and also so they can have better search features. Maybe I should...
