If you want some people to follow have a look at this list of people who I have labled as 'learning' http://twitter.com/#/list/amcunningham/learning
I'm not sure what you mean by 'follow twitter sites'. You follow accounts not sites.
It's not necessary to get any notifications my email. But I still allow notifications to my usual email address of DMs (direct messages).
How to access twitter? I think the best way is to download a desktop application such as tweetdeck. It's easiest to see everything that is happening then. But the main webpage is still manageable.
I got so caught up in looking through her list, I forgot to "follow" her! I found, though, that others had followers that were interesting. So I looked at who some of my favorite bloggers were following. One problem with this is that sometimes you loose the context of who they are, so I made sure that I also looked at their biography.
So lesson #1: make sure that you have a "vision" for twitter (just as you would for blogging) and that is evident in your biography.
Lesson #2: check out your favorite bloggers and their followers/people they follow. This helps you to create a network that will be helpful to you.
One thing that I noticed was that I had 3 readers immediately. What was odd to me was that none of them had followers and they had no tweets. This got me to wondering why they would follow someone and not tweet. One possibility is that they use twitter as a resource to find out about certain resources. At least one of my followers appears to be this as she is a marketing blogger. She may follow any one who has "communication" in their description to capture trends and resources.
Another possibility is that they too are new to Twitter and I am a follower of someone that they know, but being new to twitter don't have anything at this point to tweet (or rather are too nervous).
The third possibility is much more nefarious. Like with Linkedin or Facebook, they may want to get a large following so when they finally tweet, it will have a greater impact, putting them on the "favorites" page immediately.
Getting a following
I'm not sure how I got the initial following. However, I did get a few more followers through becoming a follower myself. This is like friending on facebook in which a person has the ability to reciprocate the "follower". I may not want to know about the person following me, so I don't feel obliged to reciprocate (nor do any of those I follow need to feel obliged).
In getting others to follow me, I need to let them know how to find me on twitter. Just like when I began blogging, I have to decide how public I want to make this. As I will be using this with my class, and I am still new to it, I decided to go with a pseudonym.
I also need to figure out how to tie my twitter account to my blog. Of course, as I write this, I realize that I should have named my twitter account something like @connecting2. Oh well, this is something I will need to work out in the future.
I would appreciate any suggestions from my readers on how to expand my following. You can also follow me (I'll post new blog post titles on twitter) at Comprof1 (that is the number 1 at the end) unless I decide to change name in the next week or so (let me know if you think I should keep what I have or change the name or create a new twitter account that is dedicated to the blog and items related to the blog).
