If you're looking for a simple way to share snippets of text and file attachments with nothing more than a shortened URL, Write.fm — from the creators of Task.fm — is a notepad with built-in file sharing.
Click on the image above for a closer look.
Originally conceived as an internal tool for the Task.fm development team to share code snippets and files, they released it for public use after seeing how well the text and file sharing tool worked for them. You can alter the shortened part of the URL to anything you want — that hasn't been taken already, of course — type or paste in text, and attach files up to 4MB in size.
You'll notice the lack of "Save" button. Whatever you write in or attach to your Write.fm sub-URL is added immediately and viewable/editable by anyone you've shared the URL with. If you want to delete the contents you do so manually, removing the text and clicking the remove button on the file attachments. Write.fm is a free service that requires no registration. If you're looking for a text sharing service with a more formal slant towards code sharing, check out previously reviewed Friendpaste. Have a text sharing service you prefer?
