The issue of usability. Which is better

We develop social programs. The next moment appeared, we can’t decide how best to:



The user views the list of articles. Suppose he sorted it by the tag "that's it yes" and is on the fifth page. Then he stumbles upon an interesting article and decides to view it in its entirety. Since we can attach a photo album with articles, he, having seen a beautiful thumbnail, pokes it and goes to the page with a photo ...



At the moment, on top of the photo he has a “path” - Topics / Very interesting topic / Photos / Photo title. Everything, except the last, is clickable. The question is: When clicking on "Topics" where should he go? To the main page of the “Topics” section or to the fifth page of the list of topics sorted by the “Wow!” Tag?

Climbing the sites in order to see how it is implemented there, I discovered the following for myself:

• Or the link "back" is completely absent. In this case, the previous page can be accessed only by clicking on the browser button "back".
• With Habr - generally a separate case. To be honest, I do not understand his navigation when viewing the topic. There are links to everything except "back." If I did not notice her, then do not scold me strongly, but tell me where she is there - I will be very grateful.
• There is a reciprocal link, but leads to the main page of the section (my version is 1).
• Backlink leads exactly where the user has gone to view the full version. This option was found only in one place - blogs on free-lance.ru. But there are no tags.

- What alternative / related options can you consider? I want to make as clear and friendly as possible for the visitor.
