Success metrics for user-reporting-errors pages

[hujambo-dunia]

With (1) the new features and enhancements around the User-Reporting Errors feature (on "Dataset Errors" and "Tool Form" Pages) and (2) because of the ability to capture error "transcripts" (ie. free-form error reporting), this could make for an straightforward way to capture some anonymous success metrics without needing to rely on the more privacy-invasive web tracking tech (ie. Google Analytics). Many of the calculations can be calculated with SQL commands accessing the smtp-mailer database directly (although some metrics may require new tracking data points and new database tables). If proven useful, this could become a part of the gxadmin repo for additional information for Galaxy Admins or it could just be for internal tracking purposes for the UseGalaxy.* sites - of course, very open to other ideas. Level of Effort (LoE) should be moderate. Below are some possible success metrics we could track which would allow us to tweak/improve those components over time:

Possible "Success Metrics":

1.0 Time to respond to error
2.0 Accuracy of error
3.0 Subsequent email replies (fewer user replies may be good, but not necessarily)
4.0 Engagement with site post-error:
4.1 Subsequent visits
4.2 Time on site post-error
4.3 Sentiment analysis

Particularly interested in thoughts for individuals currently adding enhancements to Pages where this feature appears: @jennaj @dannon @tcollins2011 @ahmedhamidawan
