Google Reader added custom "Send To" options to its feed reading service, and at least one blogger quickly patched together a Save as PDF trick. Now others have Send To links for Instapaper, default email clients, Google Calendar and more.
Jordan Running sends us his tip on sending Reader feed items to Instapaper, the article-saving, text-extracting webapp we find pretty indispensible for set-and-forget mobile reading. I'd thought using my email address as my Instapaper account would trip up Running's URL hack, but, despite landing on a 201 error page, the full article—pulled from a partial feed item—arrived in Instapaper just fine.
Over at Google Operating System, blogger Alex comes up with hacks for Google Bookmarks and Add to Any, while his commenters chime in with tricks for adding Google Calendar events, triggering your system's default mail client, like Outlook, instead of Reader's built-in Gmail sender, and a few others worth checking out.
As noted in yesterday's post, share any Reader "Send To" URL tricks you find or devise, and we'll round them up for a meatier post in due time.
