Sending web pages from Instapaper to Kindle

Actually it is difficult to call it a topic, but there is not enough karma to create a topic-link, and the news, it seems to me, is useful, so I decided to share it with the community.
The owner of the service Instapaper found the time and subdued, then what most Kindle owners have long dreamed of. Now new articles are automatically sent to the amazon reader.
UPD:

The website instapaper.com is one of the options for the “read later” service. There are not so many functions compared to the same “Read it later” , but it has a number of its highlights . The author himself positions it as a means for conveniently reading large texts (web pages) from the monitor. Especially for this, there is a button on the website and a bookmarklet for the bookmarks bar that allow you to format any page into a convenient form for reading. Another nice feature of the site is the support for sending marked pages to the Kindle. On Habré, the service was already mentioned in the article "6 great ways to keep links for later"

The main features of instapaper.com to send articles to Kinlde:

• Allows you to send up to twenty articles at a time;
• It is possible to choose to send every day or once a week;
• You can set the minimum number of articles at which all of them will be sent to the Kindle. Valid values: 1, 3, 5 and 10 articles;
• Supports sending both to kindle .com and free .kindle.com;
• Articles are sent in awz format, so all the formatting capabilities (font, font size, indents from the edge, etc.) available on kindle, unlike pdf, work for them;

Among the shortcomings, I can note the fact that it incorrectly converts some pages and as a result only a part of the text or a single title may remain from the article. But personally, my percentage of such pages is small enough to continue using the service. UPD
