MicrosoftHi AnnaChu, - yes, but... You have no counters for blogs, to know if someone commented it you may only through strips (which are not necessary on first pages) or by email (which easy to skip since I have tons of them every day), or by RSS.
For conversation spaces counter shows what something was unread (sometimes with mistakes by the way) and follow to grey strips is good enough if you have few of unread posts. If a lot of them and you have enough time to check what was new in previous few days - it's an option to open conversations in new tabs (could be dozens of them) or open conversation, return back, click few "more" and repeat again. And if you check conversations not sequentially, but first newest and most interesting, less new and less interesting with another cycle, etc - that's bit annoying. It looks like "unread" filter could help.
I usually use RSS and return to web interface if only skip a lot (RSS doesn't keep entire history), thus perhaps didn't find the best way of working with web UI - as for now it's too many clicks.
