You can't really trust bookmarks either. Most of my bookmarks are dead either because the site is now gone or because some blog author decided to change their path format and didn't bother setup 301 redirects.
Microsoft's help pages are the worst for this. "Oooh, confusing .NET problem I'll google a response - Hey, a nice forum-post explaining that MS has a document telling me how to handle this issue click NOOOOOOOOOOOOO".
There used to be a whole slew of helpful msdn (technet?) blog posts which now not only redirect but also require logging in with an MS account to read them.
It's really unhelpful.
edit: Actually I just checked and it looks like they've eased up on the need for logging in, I guess they saw too much of a backlash. (Or just flip flopped their own decision again.)
Unfortunately, this won't work on sites that robots.txt-block Internet Archive, and existing archives may be made inaccessible by a future robots.txt block.
http://archive.is/ is another useful site that executes all of the JavaScript and captures the post-JS-execution DOM.
Thank you for your information. I'm looking for tools to save my useful information like other people do. I have two problems with this type of archival tool besides the robots.txt issue:
1. The static snapshot can only give us an idea of what it looked like because it's not functioning, not updating. Better than nothing, but we may have no clue what we want to find other than a few keywords. If you need to search the entire context of the archival, everybody needs to install a mini search engine.
2. If it becomes popular like Google, so many people are going to use it, it will create so much data duplication on everybody's pc, which is helpful but not an efficient solution.
Do you like to have a self-organized personal private web on top of the public web via a few clicks? http://bit.ly/1c2DzN6
I tried Evernote. I can archive information pages into notebooks as groups and find by tags. But it cannot save dynamic product/service information with updates, and it's not self-organized. So like other online bookmarks, it's not popularly used.
