Vocaroo

Let's start this off with a quote directly from the site itself:
"Vocaroo is provided in the hope that it will be useful, however we don't accept any responsibility for anything that happens ever (be it a result of you using this service or not). If nuclear war occurs because a Vocaroo message gets lost in the ether, it's not our fault. Disclaimers are wonderful things :)"

Vocaroo.com is nifty. It is an incredibly straightforward and simple way of sending your voice to other people. You can send it to their email address or download the audio file direclty from the site. It also provides you a couple of different ways to post that sound on the internet.

It really depends on the user how much use you will get from this site. Personally, I won't use it much as I rarely need the capability of sending my audio to someone without using other tools I already have.

It would be a great thing in the future if they could add some audio effects of some kind to your recording. We'll see!

It is, however, completely ad-free and couldn't possibly be simpler to use. There are a couple of bugs, but as addressed in the very first quote, they already realize that.

REASON TO USE:
[1] You want to send a voicemail to someone's email address or just record/listen.
[2] You want to post a recording onto your own website
[3] Simple interface.

REASONS TO LOSE:
[1] Bugs during the development process
[2] If you have no need for this service
