Trying to figure out if I really need this feature. I feel like the tagging in XenMedio imports spam to my own site from YouTube and really doesn't serve a good function other than saving those dumb search terms to the database. About the regular forum tagging mod, I feel like search is good enough but then sometimes xenforo search sucks.
Outside of issue tracking for software development, or organizing something like bookmarks, I don't find tagging all that useful. I'd much rather just search, despite any shortcomings -- most people suck horribly at applying appropriate tags.
I only tag someone if I need them to view the post or they are included in the post and its important for them to see it, otherwise I don't need it. It can be useful sometimes for I would recommend keeping it.
All forum searching sucks.
Xenforo's search is the same as vB and IPB.
As craigiri recently said: forum searching is not going to beat Google.
The best current upgrade from forum searching is .. Google.
Tagging in XenMedio is probably a good thing.
When you stumble upon a video you like ... it's nice to be able to find similar other ones.
As an end-user on forums I've never used tags, and as an admin I'd not want the extra work of having to ensure content had the right tags. The only use I almost had for them was done instead by thread prefixes.
I think tags are very useful. Tags are essentially pre-made search items for people's convenience. Really, there are people who wants to search for something but don't know what to put in the search field to get the best results.
I don't think that tags help to boost SEO though.
