It has come to our attention that some visitors to our articles and blogs have been unable to post comments. Apparently, this a problem when trying to post a comment with logging in (posting as a guest) via Disqus, Twitter, OpenID or Yahoo while using Internet Explorer.
The problem lies in an incompatibility issue between Disqus and Internet Explorer and may stem from security issues with Internet Explorer. We recommend you use Firefox, Chrome or Safari to avoid these and several other issues.
You CAN post a comment using Internet Explorer, but you’ll have to login using your Disqus, Twitter, OpenID or Yahoo credentials.
IMPORTANT NOTE: If you are using Internet Explorer and try to post without logging in, Disqus will not accept the comment. If you wish to post without logging in, you must use Firefox, Chrome or Safari.
