For each of the Wikimedia projects there is a new wikistats file which shows page view counts: see following links (in order of traffic volume): Wikipedia, Wikispecial (commons, meta, etc), Wiktionary, Wikibooks, Wikiquote, Wikinews, Wikisource, Wikiversity. Each file shows monthly totals, per language and for all languages combined, a forecast for the current month, throughput per unit of time, monthly increase or decrease (percentage at top left of each cell), how much this language contributes to overall monthly total (percentage at top right of each cell) and a small chart for up to 12 months history.
These files have been generated on my home PC, but in the not so distant future they will be updated periodically from the new wikistats server, which is finally arriving (in bits and pieces).
Input for the report are the page request logs that became available starting January 2008.
If some of you find the dense presentation a bit overwhelming, no worries, like many wikistats tables the presentation can be tuned: you can omit percentages and/or color.
For most projects (the ones with many languages) there is a second table. This table shows how a small minority of language projects receives a vast majority of page requests. Over time it will hopefully also show that the distribution becomes more even (or rather reflects more proportionally the number of speakers of that language with internet access).
The following diagram shows a summary of page views per project. This diagram has been manually crafted, but other charts that give overall or per project insights are planned for addition to wikistats.
