How Many Extentions Do You Really Need?

I know the companies tell you to buy up multiple extensions, but do you really need them all? I ended up buying the .net, .com. and .org but it was too expensive to keep them all at the time so I just kept one.

The thing is will so many more extensions you can't buy them all and people can put a hyphen in or something, so there is no where of making sure no one cannot have a similar name anyhow?

 

If you want to purchase multiple domain extensions to protect your brand. It would be upsetting to put all of your hard work into your site, your branding and your products for your .com only to find out that someone else has purchased the .ca and is now competing with you. Some brands have also been faced with the downside of not purchasing all of their url extensions and finding out that someone has used a different extension to create a site to write about them.
