Almost everybody using the internet is using some “favorites” mechanism. You just need to keep the list of the useful sites, because it is becoming harder and harder every day to find one single document in the TBs published on the internet (although Google states the opposite:))
As you have probably noticed, SAP pages are not very helpful when it comes to bookmarking. For example try to bookmark two forum threads – both have the same text so the second will prompt you to overwrite the first one. I don´t like that (in fact the solution would be easy – to change the page header so you can bookmark two threads and both will have the different, something-useful-telling, captions, right?).
By the way – trying to remember all the useful SDN threads in your browser bookmarks or in a text file (I have tried both) – is not what i would call friendly or usable. Same with the blogs.
Let me take a step aside: some time ago I wanted to publish a blog post which was not very “innovative”, but was (imho) useful for the beginners – a link list (like 20 links you need to read) for one certain field (Adobe forms). My blog post was refused. I can understand that, I can live with that (but we all know some people are allowed to post these blogs, right?:)) I was asked to write a wiki page. I am not going to do this and many people around don´t use wikis because they want to be the exclusive owners of the content (but that is for another story).
But if there was an option to maintain my bookmarks list on SDN (well, that could be a part of the business card, what do you think about that?), I could just publish my link list (“tagged” content) to help the people start and don´t have to argue about the blog or have to write a wiki page.
At the moment, you can watch the thread. I use that when I expect anybody to add something useful to a thread. I use that that to watch the Adobe forms related questions outside the proper forum (you can find many of the question in ABAP Printing or even ABAP General). That is not what I am talking about here – imho that is used in different situations and it cannot be published. Of course you cannot “tag” all the content you would like to with the “watch XY” option.
If such a thing would be available on SDN (shared tagging in a business card for example), I would use that not only for “tagging” content for myself and maybe some people following me, I would also use that for searching. I know people here on SDN who are true experts in their fields and I am sure I would find the best content available through searching their “tagged” content.
If one can hit the abuse button, he can also judge if the content is useful for him. This way, through the authority of the people we believe in, we can get access to the true treasury of the SDN content.
