I think you are referencing a different extension, not made by Amazon. That’s going to be confusing for a lot of people. The one that’s been around is from klip.me…and is called just “Send to Kindle”. The official Amazon one is “Send to Kindle for Chrome”, I believe.

I think it’s possible Amazon will force Klip.me to change the name of theirs, even though it was around first. Amazon has gotten people to change their website names and such for including “Kindle” in the domain. This is different, but we’ll see what happens.

I’ll update the article to clarify that…other people are mentioning that.

Personally I use Pocket which does what send to kindle does, but stores it on their own web site without the 5GB limitation, and it has some useful categorization and tagging capabilities of the stuff you save — it also lets you keep track of read/unread status. Pocket is a chrome extension on the chrome side, and works in conjunction with a Pocket app on the Kindle Fire side (yes, it only works on the KF, whereas the Amazon extension works with any kindle or reading app.)

One big thing that Pocket let’s me do is right click on links within a page, and save what’s “behind” the link — very handy for processing emails or web pages which are largely lists of links to possibly interesting articles that you might want to read later.

Pocket also works with Google Reader to let you save items in RSS feeds to be read later.

Once an article is read on pocket, you can leave it on your Pocket account in perpetuity, or share it out to some other (usually social networking) site, or send it via email to another destination of your choice. The Pocket approach also has the advantage of only using KF memory sufficient to hold just the article currently being read — all long term article/document storage is in the cloud on the pocket site. Send to kindle keeps stuff in personal documents, many of which could at any point in time be downloaded on your kindle and consuming thereby scarce memory.

I always enjoy reading about your views on physical books, especially considering your experience with book selling. Keep up the good work!
