...the title of the post is "make big money". In the tag area I'm adding make big money, or tools to make big money, or how does blogging make big money.
When you ask "...OK to use with all the Google updates?", presumably you are asking whether these would be perceived as spam?
I don't think it is necessarily the subject matter that is a problem (although admittedly "make money" scams certainly ride high on the spam-o-meter, so you are playing in a dodgy area from the off). If that is your subject then so be it, it could be legitimate and a great resource for many.
However, it does look like you are keyword stuffing and in that sense it looks "spammy" IMO. You include the same 3 keywords in each of your tags, "make big money". If it wasn't for trying to get ranked in search engines, including the same keywords in multiple tags has little benefit to users.
All those different tags go to the same post page.
Others have already mentioned the possible duplicate content issue. Admittedly I thought you were talking about the actual "posts" at first, which obviously won't be perceived as duplicate since there is only one post with one canonical URL. However, as I was corrected in comments, if multiple posts have the same tags then the "tag pages" could be the same (showing the same posts) and therefore seen as duplicate.
However, as I state in the comments, duplicate content is not a "penalty". It will simply mean that the duplicate page won't appear in the SERPs, but one of them could. So, for a dynamic "tag page" is this really a bad thing? If there are only a few duplicate pages of this nature then personally I would have said this was probably OK. If, however, you have 100's of duplicate tag pages (but are you really assigning the same tags to all your posts?!) then maybe it is more of a problem and you should perhaps block these as Sidh suggests.
