Twitter stealth technology ?

Is Twitter a technology that is emerging by stealth. In recent months I've seen:-

• Teachers asking for ideas for teaching classes
• Travellers asking for restaurant and things to do ideas
• Conference attendees broadcasting thoughts ideas
• Conference presenters asking questions of the audience in the room and in the wider world via Twitter
  
• Bloggers getting ideas from twitter
  
• Facebook users using it to update status and Twitter at the same time
  

Google is still the search engine of the masses but for specialist questions amongst a circle of friends (followers in Twitter terms) Twitter is a very powerful tool that is creeping up in its use.

You may only have 160 characters but it encourages short targeted questions

See you on Twitter ;-)
