I am going to collect my problems when using this platform. I already did some posts in the forum. But according to TA, it is also a good idea to post in your own journal as well. I also need a place to put all the words I said since there doesn't seem to be a clear way to pull together your posts automatically with this platform.

I need to be able to go directly to posts, replies, and votes that are displayed on my profile page (and on others' profile pages as well). This will help me to see my posts, also help me to know about other people. Is this a TA function now?

Automatic preview function is pretty good though. Keeping clicking on preview button has been a pain in the neck for me when writing blogs.

Also it seems that I can revise my message even after sending it (and before the recipient reading it). Is that true? If so, I wonder if it really works well. Ok, I just tried it again. It is just that the input box didn't disappear after submission. So it is a bug instead of a feature. :)

The instant search feature often returns unrelated entries (those listed under the search box), and thus it doesn't seem to be helpful (to me at this moment). I know with the current state of the art it is very easy to have a satisfactory result. I wanted to implement the same feature on my own site as well. But I think to have a satisfactory result, you will need a very large database, put a lot of sentences in from Internet and compute the statistics of how words are related and so on. If google can do that and provide a public service api, that will be nice.

It looks that in journal the ordering of replies is earlier replies appear at the bottom while in the forum earlier replies appear at the top. Why don't unify these two?

There is no way to delete a journal post? I know journal posts that are assignment submission cannot be deleted. But how about other posts?

As for the peer review process, the rubric appears very inadequate and it is really hard to reflect the value of the work just by those rubric. For example, what I value is whether the scenario is fake/self-created or authentic/real challenge, whether the submitter understand the scope and depth of the problem, whether s/he can see the true nature of the problem and is able to analyze it and provide some solutions. But solely from the rubric, it is hard to reflect these. Also for each scenario, how it can be described can be quite different. The simple rubric is too stiff to apply to every situation.

Also regarding voting whether I think others' feedback useful. If I vote "You found this feedback helpful", does it mean I agree with all s/he has said? What about I only agree with one of her/his points but not other points?

In general, I feel that it is very difficult for the teacher to give each student effective instruction, and that is is very difficult for students to learn together with other students (since it is so hard to know what other people are doing). I think the teacher and TAs all have a quite difficult time in knowing all the learning conditions of the students or their interests. Well, that is what Knowledge Engine is for.

Last, the most valuable thing I found with this platform is that the esteem of Stanford University is able to draw people from around the world and from various areas of learning/education together. I have found some interesting people doing interesting projects here. The setback is that the platform is so in-effective in finding interesting people and projects, and it is very hard to accumulate knowledge and share/transfer knowledge here.
