The Internet Archive discovers and captures web pages through many different web crawls.
At any given time several distinct crawls are running, some for months, and some every day or longer.
View the web archive through the Wayback Machine.
Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.
Liveweb proxy is a component of Internet Archive’s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.

Favorites, represented by a small star icon in a Tweet, are most commonly used when users like a Tweet. Favoriting a Tweet can let the original poster know that you liked their Tweet, or you can save the Tweet for later.
To mark a Tweet as a favorite:
Make sure you are signed in to Twitter.
Hover over the Tweet you'd like to favorite.
Click on the star icon and it will turn gold, confirming that you've favorited the Tweet.
You can also favorite a Tweet from a user's profile page and a Tweet's permalink page.
Note: If you mark Tweets from users with protected profiles as favorites, the update will not appear in the Favorites tab on your profile page (unless the viewer is an approved follower of the Tweet's author).
To undo or remove a favorite:
Make sure you are signed in to Twitter.
Find the Tweet you favorited (the star icon will be gold).
