Squidcasts do get overused however and if I get 20 squidcasts all at once from one person I won’t be checking out their lenses. I do go into the my favorites tag everyday to view my squidcasts so I’m sure other people do as well.
Now you can get an rss feed of your squidcasts from squidutils and I’ve actually added this to my lensography so that it keeps that updated regularly. Now apparently Google looks at your squidcasts as well so it’s a good idea to add keywords into the title and body of your squidcasts…..this is another failure of mine, but we can (hopefully) all learn from it.
In a nutshell think of your squidcasts as blogs and post small, but good seo based, posts everyday.
