I thought it would be good to highlight some of the better file sharing websites available. I've noticed a lot of people use terrible sites to host files. Websites like Rapidshare, Megaupload, or Sendspace are absolutely trash, with a lot of restrictions, stupid download delays, crappy interface, and pushing you to subscribe at any chance they get. Even slightly newer/better popular sites like 4shared are still not up to snuff.
I think these sites are popular because they were here first, but there are many great (free) alternatives.
1- MediaFire (www.mediafire.com)
MediaFire is getting very popular, and I see it being used more every day. Thanks to a simple interface and no nag screens, you can easily share links and keep a library of files. They still push their paid model, but they don't bug you about your IP address or make you wait 20 seconds to download.
Upside: No signup required. Unlimited storage.
Downside: 100 MB per file limit. Ads.
2- Box.net (www.box.net)
Box.net was one of the first leaders in offering a new, clean, nag free model. Today I would only recommend it if you have a library of files less than 25MB each in size, and would like to share it with a group and be able to modify the files.
Upside: Great interface, sharing and collaboration features.
Downside: Registration required. Better features are pay only.
3- Drop.io (www.drop.io)
I saved the best for last. This is by far my favorite storage solution, and I'm surprised many people don't know about it. Drop.io is a fast, simple, clean, and efficient way to share files. Just go to thier website, and in two clicks your file will be uploaded. I even have a Firefox extension which integrates it with my browser for drag-and-drop operations.
They've recently introduced a pay model, while keeping the base service free as it always was. The pay model is the best I've seen so far as well.
Upside: Too many to list here.
Downside: 100 MB max file size.
Special Feature Note: Drop.io offers a "Paywall", which allows you to charge users. This way a group of users can upgrade to the better storage plan, for example paying $20 per year, and then each user will pay $1 and as more people join the drop can be upgraded. It might be something we can look at collectively in this forum, to have a permanent Inter media storage.
Honorable mention: Orbitfiles.com - seems like a great service, I just don't trust them yet.
Finally, I hope nobody ever uses Rapidsh*t and co anymore, and I hope I've demonstrated why these options are better than 4shared. Ultimately, the best option is a paid solution, but for now I recommend everyone sticks with Drop.io.
