I recommend you follow Dan Meyer if you dig the web and/or teaching and/or presenting and/or math. He’s great.

I like how his post included below shows that even if you post to Twitter or share via Delicious, you should still have a blog. I would add:

• Use Tumblr because it’s simple, easy, free, hosted, and offers wide fast flashing of cool stuff via its Reblog feature.
• I see much cool content hitting Facebook these days. Don’t post such stuff first to Facebook, today’s AOL (i.e it’s an easy-onramp to social media and web publishing, but it’s a walled garden where Facebook dominates the context.) Even if you post lots of content to Facebook, get up on Tumblr. Post first here, then cross-post to Facebook. Tumblr lets you control the context, supports RSS, offers reblogging, etc. It’s better.
• Even if you have WordPress or some other fully-featured awesome blog, get up on Tumblr. As they say, if your blog is your journal, think of Tumblr as your scrapbook.

Here’s Dan sharing a video he likes and speaking to the different utilities of certain web tools:

Vanishing Point

January 24th, 2010 by Dan Meyer

I tweeted this video two days ago. I tagged it on delicious a day ago. Short of driving to your house and forcing you to watch these 100 seconds of abstract geometric bliss, this is all I can do:

I still may drive to your house.

If you only throw something at Twitter, it will likely have about ten minutes to catch and spread.  Delicious helps share bookmarks but does not include video embeds.  A blog lets you embed media without character limits, and it lasts longer since many may read your post much later via RSS.  Tumblr, again, is free and easy and makes reblogging cool stuff (from other Tumblrs) as easy as pressing a button.

Follow Dan. Let me know when you arrive at Tumblr. Have fun.
