Try searching for the article title on Twitter and using the most popular hashtag from the results. It's riskier, in that you might end up using an offensive hashtag or missing the context or using a hashtag that actually is unrelated to the topic... but more often than not, this approach works pretty well. @FixmeBot has gotten quite a bit more engagement since implementing it.

Here's how I did it in Ruby: https://github.com/ragesoss/FixmeBot/blob/master/app/main/twitter_client.rb#L12

Adding a ?gettingStartedReturn=true parameter to the WP link will trigger an onboarding worfklow (on editable pages) which should help new users find their way through the editing process.

I noticed that on a few occasions – likely because of some weirdness with the names of templates used on talk pages – the string WikiProject is included in the string, we should probably strip exact matches. See:

Special characters break hashtags:

We might replace characters like "&" that we can't strip without altering the meaning of the hashtag, see https://twitter.com/wpstubs/status/496151412510695424

Some special characters are rendered incorrectly, e.g. "Can't You Hear the Song?" [1]

Coordination projects should be blacklisted so they do not generate hashtags, e.g. #Articlesforcreation

This is an interesting case: https://twitter.com/wpstubs/status/496130737070829568

A B-class article already included in multiple WikiProjects was recently added to another WikiProject unassessed, which triggered a "new stub" message. We should think of some simple heuristic to avoid this issue.

I realized that the wording used in the tweets ("Someone just created a Wikipedia article about X") is misleading: there's often a considerable lag between the article creation and its inclusion in a WikiProject. "Someone created X a Wikipedia article about X" is much safer :)
