One software package I’ve been finding useful lately is Evernote. It’s a free note-taking service with plenty of ways to access it. You get a web app, a Macintosh client, a Windows client, a Windows Mobile app, and an iPhone app. Your notes are synced up to Evernote’s servers, where you are allotted a certain amount of monthly storage space. If you’re like me and mainly use plain-text notes, you probably will never run into the limit.
Of course, you’re not limited to text notes, and that’s how Evernote gets you to buy their $5/month premium service. You can store web clippings, photos from your cameraphone or other source, and even audio recordings.
You can separate your notes into different “notebooks,” and optionally create tags to further organize them. A search function lets you easily find the one note you want out of the crowd. You can also designate that some notebooks be publicly viewable.
It’s quite an interesting service, and it’s free unless you become really addicted to it and use the photo and audio note options quite frequently. It’s definitely worth a look. I use it to keep track of ideas for posts here on Webmaster-Source and on other blogs, and for anything else I need to remember. Instead of carrying a small notepad around with me, I now carry my iPod Touch and use Evernote.
