Tumblr has been a surprise hit blogging service, giving users the ability to easily share pictures and pithy posts inside their ecosystem. Up to this point, the company had shied away from major efforts to monetize their operations. Aside from a selection of premium blog layouts, the entire service has been free to use since day one. That changed today when Tumblr announced new “highlighted posts,” which for a small fee aim to draw user’s attention.

If you’re anything like me, you’re constantly looking for new ways to tap into your distilled reserves of video game nostaliga. Mapstalgia, a thriving new Tumblr that popped up a few days ago, seems to be the perfect, unusual-but-effective way to do that. It’s my nostalgia drug of the morning. The premise is simple: People draw video game maps from memory, but somehow the result is so much more than that.

Single-serving Tumblr The Same Picture of Dave Coulier Every Day posts the same picture of Dave Coulier every day. It might also be home to the only Dave Coulier favicon on the Internet. Either Tumblr must be crowned King of the Comedy-Based Internet, or it must be stopped. It is difficult to tell which is the better option.

It began with a simple request over Tumblr. The proprietor of My Life as Rebekah was asked, “can you draw a shark who’s addicted to the internet?” The response is truly wonderful, combining all the best of obsessive sharing platforms like Twitter and Tumblr with Shark Week and Disney’s The Little Mermaid. This veritable pop culture cavalcade coalesced into a fantastic comic strip which will have you humming Part of Your World for the rest of the day.

How wonderful, you ask? Read on below. I assure you, you will not be disappointed. 

The joke in the blogosphere is that the Internet “comes from” only a handful of places. This chart created by webcomic Endless Origami doesn’t teach you where to find content, but helps you choose which source for what ultimately ends up being the same pool of content is right for you. Granted, the chart leaves out neat geek culture blogs that sift through all the rabble to cull the top content, and generally also has some pretty killer original content of its own.

This looks promising: Literally Unbelievable is a new Tumblr that screencaps outraged Facebook comments on Onion articles from people who either haven’t noticed that the article in question is from The Onion or simply don’t know that The Onion is a satirical publication.

As it so happens, there are a lot of these people. The blog’s creator writes: “I curate the site and wanted to make it clear that these people are being completely earnest. Certainly I saw a good number that were inside jokes, ironic posts or trolling, but the ones I posted are 100% the real deal.”

Earlier this week, mobile photo-sharing and effects application Instagram let it slip that it has chalked up an impressive 4.25 million users: Not bad for an app that launched just 7 months ago. For all of its traction, Instagram (and Tumblr, where many Instagram pictures eventually find their homes) is stereotypically associated with overfiltered photos laid over with cryptic, faux-profound text. One humorous Internet trend that has arisen in response is to point out the silliness of pretentious Instagram pictures by rudely splashing red text on them.

Because our RSS readers are so overbrimming with awesome stuff that we can’t fit all of it on the site, Twitter, or Facebook — although the people who follow us on other platforms find it a profoundly enriching experience — Geekosystem has dusted off its formerly defunct Tumblr account. You can find it at http://geekosystem.tumblr.com/, where every day, we will be posting and linking a few of the cool and interesting things we find across the Web and reblogging our favorite Tumblrs and sites.

It was only a few short days ago that artist Matthew Inman, aka The Oatmeal, had his State of the Web making the rounds. In it were chronicled major internet events of the past year, and one stirring recommendation: Tumblr needs a FailWhale equivalent. In a startling turn of events, Tumblr has honored that plea.

In the early days (ca. 2008), a lil’ microblogging service called Twitter could barely keep itself online and addressed these issues by making their 503 error page an adorable image of a whale sinking the internet. The FailWhale has since become the thing of internet legend. Fast forward a few years and another microblogging site, Tumblr, begins to grow in popularity. As it does, it too begins to fail with such regularity that you could set your watch by it.

And now, the Tumblbeasts have been unleashed; hopefully soothing frayed Tumblr users’ nerves with their adorable green antics. Beware the TumblBeast, my son! The jaws that bite, the claws that catch!

Oops! Accidental reboot! This has been making its way through Tumblr, the earliest appearance on user jacquelineofalltrades’ stream. We’re unsure of the originator, but if we did know, we’d salute them here ——> ______. (Thanks, Pete!)
