Add rel="nofollow" to .Text comments

Thomas Freudenberg — Wed, 19 Jan 2005 14:15:00 GMT

Today Google, Yahoo, MSN Search, and other search operators announced their support of the rel="nofollow" attribute for <a href="..." /> tags. Adding this attribute indicates the search crawlers, that the specific links should not contribute to the linked site's page rank. This might help fighting comment spam, since overwhelming blogs with comments containing links to any pharmaceutical site won't increase their search rank.

Whether this will help to fight comment spam or not, time will show. Anyway, I've written a small plug-in for .Text, which adds the mentioned attribute to all links in comments.

Some time ago Scott Watermasysk has described who to add custom entry handlers to .Text v.96. According to these instructions, my entry handler looks as follows:

.csharpcode { font-size: 10pt; color: black; font-family: Courier New , Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0px; } .rem { color: #008000; } .kwrd { color: #0000ff; } .str { color: #006080; } .op { color: #0000c0; } .preproc { color: #cc6633; } .asp { background-color: #ffff00; } .html { color: #800000; } .attr { color: #ff0000; } .alt { background-color: #f4f4f4; width: 100%; margin: 0px; } .lnum { color: #606060; }

    public class NoFollowFormatHandler : IEntryFactoryHandler
    {
        public NoFollowFormatHandler()
        {}
        public void Configure()
        {}
        public void Process(Entry entry)
        {
            entry.Body = ReformatLinks(entry.Body);
        }
        private string ReformatLinks(string text)
        {
            return text.Replace(
                "<a target=\"_new\" href=\"",
                "<a target=\"_new\" rel=\"nofollow\" href=\"");
        }
    }

Afterwards, you have to add this handler to the event handler configuration section in your web.config, in fact after the default handler:

<EntryHandlers>
    <EntryHandler
        type="Dottext.Framework.EntryHandling.CommentFormatHandler, Dottext.Framework"
        postType="Comment" processAction="Insert" processState="PreCommit"
        isAsync="false" />
    <EntryHandler
        type="Dottext.NoFollow.NoFollowFormatHandler, Dottext.NoFollow"
        postType="Comment" processAction="Insert" processState="PreCommit"
        isAsync="false" />
    <EntryHandler
        type="Dottext.Framework.EntryHandling.CommentDeliveryHandler, Dottext.Framework"
        postType="Comment" processAction="Insert" processState="PostCommit"
        isAsync="true" />
    ...

That's it. You may either download the source code, or just get the compiled assembly and copy it to your bin folder. Add the handler in the web.config, and all links in new comments will have the rel="nofollow" attribute.

Be aware, that this solution targets .Text v.96 only. V.95 does not have entry handlers, so please don't bother me with asking for a .95 version.

Blog citation search engines

Jeff Sandquist (yes, the nice guy who sent me a t-shirt) compares blog citation search engines, i.e. Bloglines Citations, Feedster Links and Technorati. He asks you to test them and leave a comment on his blog.

I've searched for http://thomasfreudenberg.com/blog on all of them, and Bloglines Citations returned the best and most results.

FeedValidator does not like me

Thomas Freudenberg — Sat, 13 Sep 2003 02:53:00 GMT

It seemed as Feed Validator didn't like me. When I checked it said it can't validate my RSS feed. However, loading my feed within a web browser looked ok. Therefore, I wrote an email to Mark and Sam this morning. I've got following reply:

Yeah, that's a known bug. It's not your fault at all. It's a server configuration issue on the new server, and Sam and I are actively working on a fix. (It affects his feed too.)

Thanks for the report. We'll announce at http://feedvalidator.org/news/ when we have a fix.

-Mark

Thanks in advance, Mark.

PS: BTW, I cannot find a RSS feed for the Feed Validator News

Blogger free for everyone

What's up at bloggers:

Free Features for Everyone Good news, folks! The feature wagon just arrived and dropped off a host of bloggity goodness at rock-bottom prices. And we're passing the savings on to you! That is, we're rolling in a bunch of features that will give you more powerful and flexible publishing power (for free). Want to know what's included?

Seems as the buyout by Google pays off. Most of the features, which required a Pro account ($35 p.a.) till now, are free for everyone.
