Still other like options: Have a 'like' button that is similar to a poll.
>It would never appear in a LJ's general profile,Avatar or in the pulse header of a thread, blog, or project post. (This would help discourage 'LIKE hunters', and keep newbs from being intimidated from sharing input, or posting on certain threads)
>In the body of a forum, blog, or project post, if
A1Jim comments on a great method for clamping a glue up I could hit a 'like' or 'caution' button
>I would then be prompted to comment on why I made my selection, and those comments would be added to the thread. (this is similar to the +1's that are going on right now, and no 'Lazy' votes)
>A like and/or caution icon would appear on
A1's post, and possibly in the header.
>If I hover over the icon it displays the Avatar and name of those who liked or cautioned. (no anonymous votes!)
>If I click on the Avatar it takes me to that specific comment. (Like the links some have asked for)
>Once someone likes or cautions in a thread post, the option is given in the original post to see all likes, see all cautions, see all comments. (additional sorting options for reading threads) (maybe a 'joke' button if you just want to see all the 'smarta$$' comments

The creator of a thread would have the ability to disable likes and cautions, or even hiding just the counter at the thread heading, giving them the control of how they want to build their 'crowd' in the 'community'
>The poll option would still be a valid option.
There are versions of these ideas present in several of the forums I participate in (not all woodworking), but not all together. I think it could preserve the look, flow, and community by discussion, not expertise, that is present in LJ's, while providing the option to both poll, rate expert advice, without creating 'experts', and upgrade the sorting and readability of long opinion based threads.
IMHO there are very good arguments on both sides of the 'LIKE' button argument. Why not 'LIKE' our cake and eat it too!!
