This "new to Twitter" post helps new Tweeters find technology Tweeters to follow from Day 1.  Sign up for a Twitter account if you don't already have one then visit a short list of recommended technology-related Twitter accounts.

Martin: hope this helps.

If you want, try using the button below.  I think it lets you call anyone in the US or Canada if you have a microphone and speakers.  If you know my phone number, you can try calling me :)

Small businesses can publish their own phone numbers next to their own buttons like this one, giving potential customers a mind numbingly easy way to call when they otherwise might be too lazy to pick up a phone.

I set this up using Google Voice's handy widget on a tip from Ryan.

• Related Background Post: Allow Public gChat for Instant Gratification
  

This post is for bloggers and small businesses that want to make themselves more accessible than most and perhaps impress their readers.  To make this work, you will need

• A Google Talk account (gChat within Gmail is fine)
• A web publisher that allows you to insert custom HTML.  I have done what follows with Weebly and Wordpress, although I imagine Posterous and other publishers allow you to do so as well.

Next,

1. Visit http://www.google.com/talk/service/badge/New (link opens new window) to generate your custom created code.  Copy it.
   
2. Paste this into a web editor's "custom html" box.
3. Enjoy instant accessibility
   

Just like that, you've got a Google Chat button that allows web visitors to instantly message you as a "Guest" without signing up for Google Chat or any other messenger.  As the poster, you will not know who your reader is since they have not logged in to any accounts.  Likewise, your reader will not know your email address.  The benefit here is inspiring potential customers or readers to reach out when they otherwise might not.

I recognize this technique is more advanced than some other postings but still consider it "intermediate" in that you only need to copy and paste code, not write your own.

UPDATE 10/4/2010: Feedback on this one is coming in fast and furious.  Thanks to Ryan U. for bringing this Google VOICE widget to my attention.
