Thank you for your feedback.
The site design is something that some people would like to change. Changing to an arbitrary new design may mean to some people will like it and others will dislike it.
To minimize the problem, it is planned to make available a tool that will let anybody propose a new design. Then the users will vote for the best design. The winning design will be used from then on. The winner will earn a money prize as a sort of payment for his contribution.
As for the site load, most of it is caused by advertising. Unfortunately the site cannot live without the advertising revenue. Fortunately there is an alternative for those that would like that the advertising not slow down the site pages load nor distracts the users. If you get a premium subscription, one of the benefits is to access the site without advertising.
Premium subscriptions cost a small fee which is enough to offset from the loss of advertising revenue. And you still can benefit from other exclusive services. If you are interested in these services, you may want to take a look at the premium services page also mentioned in the article:

I agree that the redirect delay is too big. The problem is that Google suggested that pages should not redirect users to other pages too fast as that characterizes cloaking and that is a banned practice.
I don't know what is redirecting the users too fast. I thought 5 seconds was not too fast. I wonder much can I reduce it. If anybody has more information on this, it will be appreciated if you could share it.
Other than that, rest assured that your criticism is appreciated. It just shows that you care to improve this site. Feel free to submit more criticism or improvement suggestions if you would like that.
